Problem 6 Using analytical expressions show why we need stronger brakes on the front wheels and why rear wheel drive cars accelerate better.

Solution

When the bicycle starts to decelerate, weight transfers forward onto the front wheel. This weight shift gives the front wheel much more traction than the rear wheel, making you think the front brake is \"stronger\" even though it is not. It\'s all about weight transfer, not stronger or weaker brakes.

You can prove this to yourself by walking your bike forward and pulling the front brake. If you pull hard enough, the rear wheel will come off the ground. Then walk the bike backwards and pull the rear brake. You will find that the rear brake now feels like the \"stronger\" brake, able to easily lift the front wheel off the ground.
