Strictly Aero

Intro - 

"An aerodynamic automobile will integrate the wheel arcs and lights into the overall shape to reduce drag. It will be streamlined; for example, it does not have sharp edges crossing the wind stream above the windshield and will feature a sort of tail called a fastback or liftback. The air that rams into the engine bay, is used for cooling, combustion, and for passengers, then reaccelerated by a nozzle and then ejected under the floor. For mid and rear engines air is decelerated and pressurized in a diffuser, loses some pressure as it passes the engine bay, and fills the slipstream. These cars need a seal between the low pressure region around the wheels and the high pressure around the gearbox. They all have a closed engine bay floor. The suspension is either streamlined or retracted. Door handles, the antenna, and roof rails can have a streamlined shape. The side mirror can only have a round fairing as a nose. Air flow through the wheel-bays is said to increase drag though race cars need it for brake cooling and many cars emit the air from the radiator into the wheel bay."

A wealth of ideas here, however, these designs render useless without considerable calculations/data analyst/testing.

Bulk On A Budget

Those gains.


Blinded as I be, enlightenment was all I seek.
Through hazy skies and waters deep,
From dusk to dawn, emotions bleak.
She sways my heart, restarts its beat,
Stirs a soul which moves my feet.
I try and try to hush its pace,
But once it starts, it ends a race.
A loser whom has lost his prize,
A part of me has surely died.
Though yet and still they may critique,
But enlightenment was all I seek

Almost There

The last week has been crazy hectic! With midterms, and preparing the car for U of T shootout this saturday.
We went went from electroinc shift to a complete overhaul and change to mechanical shifter. The exhaust was remade and almost finished. Cooling systems are golden and now just about finished the body/tiny bits.
I'm typing on almost no sleep. All nighters almost every night this week. Competition at Mosport in about 6hrs. Weeee!
Getting dat dere work doneskii
Lol, sleeppp
Created a linkage for the new mechanical shifter 
Waiting to have stuff 3D printed
Came up with this idea for the exhaust system. 
Here's what the actual stainless steel version turned out  to become. Sexy!

What in the actual flying fuck....

Late Nights/Early Mornings

As I research articles, study for midterms and acquire various amounts of knowledge throughout random internet forums, I enjoy the sweet sounds of a little jazz/bossonova.

And perhaps thoughts of a future asylum

Alas, I shall continue working hard.

Good day -

Formula SAE offers and ideal opportunity to sharpen the organization, creativity, and teamwork skills of the engineers of the future."

Updates and Guitar Solo's

Decided to upload a video I made a few months back. I'm not the greatest at playing, or singing, however I managed to pull it off haha.

Yes I am aware that this is an electric guitar..without an amp.

For What It's Worth

As time does pass she drowns in shadows,

I wish to help, yet wade in waters shallow.

The chains that confine covered in rust,

A love so unrivalled opposed to lust.

The day will come when she witnesses light,

And I will be there to emphasize the bright.

So here I wait and pray, through thick and thin,

For the day us lovers do meet again.

Steady heart which beats so slow, 

How I beg, please don't plateau.

Yet, as time does pass, she drowns in shadows.

Fight To Succeed

"To do something well is so worthwhile that to die trying to do it better cannot be foolhardy. It would be a waste of life to do nothing with one's ability, for I feel that life is measured in achievement, not in years alone."

Samsung Galaxy Round + Galaxy Gear

Galaxy Round

After a flood of rumours, Samsung has unveiled the Galaxy Round: the world’s first smartphone to eschew a flat display in favour of a horizontal concave curve.

Running Android 4.3 with its own proprietary Touch Wiz interface, the Galaxy Round comes powered by a 2.3GHz MSM 8974 quad-core processor – with 32GB of internal storage and 3MB of RAM – and sports a 5.7″ 1080p HD display and weighs in at just 5.4 ounces with a slim 0.3″ thick profile. Like the S4 and Note 3, the Galaxy round features a 13MP camera with autofocus and flash in addition to a 2MP forward-facing camera. Highlighted by the design are brand new “roll” and “gravity” effects that expand gesturing by allowing users to access glance and music-centric screens with a rock of the device. Samsung’s Galaxy Round is set to first launch in Korea before making its way to additional markets.

Galaxy Gear

Samsung‘s latest commercial for the Galaxy Gear, which recently aired during week 5 of the NFL season, takes viewers on a nostalgic journey through the most iconic wrist-worn devices featured on the big-screen and television. With devices from The Jetsons, Mighty Morphin Power Rangers, Knight Rider, Predator and Star Trek to name but a few making an appearance, the promo concludes with a 360-degree look at Samsung’s latest innovation and a tagline that reads ”it’s finally real.” Check out the commercial below featuring scenes from films and TV series that inspired the Galaxy Gear “evolution.”

Helical Limited Slip Differential - How It Works

Before explaining how the limited-slip action works, let's look at how the differential part works. 

When you go around a corner, the inside wheels have less ground to cover than the outside wheels, so naturally, they spin more slowly. The differential's job is simply to allow the two drive wheels to turn at different speeds while still staying mechanically connected to the gearbox. 

When the car is going straight, the differential itself spins at the same speed as the wheels, and from your point of view as an honorary differential, all the gears inside are stationary. When the car goes around a corner and one wheel has to go faster than the other, all you'd see, as a differential, is the two axles turning in opposite directions. 

Now look at the diagram of the Quaife differential and imagine the sun gear in front (the gears attached to the axles are called sun gears) turning clockwise. The pinion gears around the outside of the sun gear therefore turn counterclockwise. The pinion gears from one side of the differential mesh with pinion gears from the other side, so they turn clockwise, and those pinion gears turn the sun gear on the far side counterclockwise. That, if you've lost track, means it's turning in the opposite direction from the sun gear in front, which is just what you, as a differential, want to see when you're going around a corner. 

Coasting around that corner, there's no load transmitted through any of these gears, but hit the throttle and things get complicated. Look closely at what happens when the differential tries to drive the wheels. Assuming the car is going straight and there's equal grip on both wheels, the differential housing turns, which forces the pinion gears, trapped in little pockets around the perimeter of the diff, to move with it. These pinion gears are meshed with the sun gears, and because none of the gears are turning (relative to the diff housing, that is), the sun gears have to follow along, spinning at the same speed as the differential. 

The gear teeth can only push on each other with a force directly perpendicular to the face of the tooth, so if the tooth is angled, so is the force on the gear teeth. 

Now, the pinion gears don't rotate on a shaft; instead, they sit in tight-fitting pockets, with the tips of their gear teeth rubbing on the inner walls of each pocket. When the differential housing turns and the pinion gears push on the sun gears, the pinion gears get shoved back against the walls of their pockets. Of course, the more torque that gets applied, the harder they get shoved against the wall. 

That's going to be very important in a second. 

When one wheel loses grip and tries to spin, all the gears have to start turning, just as they did when we were coasting around a corner, but now that the pinion gears are being shoved against the walls of their pockets, there's some resistance. This is just the beginning of the resistance, though. In the middle, where the pinion gears mesh and the pinion on the gripping side tries to turn the pinion on the slipping side, something interesting happens. 

The pinion gears are cut with helical gear teeth that mesh at an angle. When these angled teeth push against each other, the angle of the teeth causes them to pull each other up against the end of their pockets. 

The combined friction of the tip of the pinion gear teeth rubbing against the pocket walls and the ends of the pinions rubbing against the ends of the pockets actually creates enough resistance to prevent the inside tire from spinning. 

When designing a new application, engineers can adjust the amount of resistance in the diff by changing the shape of the gear teeth and the angle of the helical pinion gears. To see how this works, just look closely at the interface between two gear teeth, starting with gear tooth No. 1 on the left. The bottom tooth is pushing up with a force represented by the little green arrow. At the gear tooth interface, the bottom tooth pushes up on the top tooth with that same force (but now the arrow is white), and if there's enough resistance on the other gear, the top tooth will push back with the same force. 

The gear teeth can only push on each other with a force directly perpendicular to the face of the tooth, so if the tooth is angled, so is the force on the gear teeth (the white arrow). In gear tooth No. 2, you can see the white arrow is now angled. This same force can be looked at as two forces, one pushing up (green), and one pushing to the side (red). As the angle of the teeth gets steeper, as in gear tooth No. 3, the amount of force pushing to the side increases. The force shoving the pinion gears into the pocket wall comes, in part, from these little red arrows. 

The majority of the resistance and virtually all of the tuning happens when the angle of the helical pinion gear teeth is changed. A steeper helix translates directly into bigger red arrows shoving the pinion gears into the end of the pockets. If there's no resistance from the gear on top, the gears will simply turn and there won't be any red arrows at all. No red arrows mean no limited slip, so if one wheel is completely off the ground, the diff will act as an open differential.
