What the brake lever does is that it use the action of the rider pulling on the lever into a force that can be used to slow the wheel(s) down by generating friction.
Yes. A bicycles braking system utilizes a series of levers to control the bicycles speed.
Because to actuate the brake you pull at the brake lever.
Bicycle brakes are usually levers
the handlebars are a first class lever. the fulcrum (the balance point) is in the middle.
Because bicycle brakes use levers. There's one lever at the handlebar, and for all but hydraulic brakes either the brake itself consists of levers or a lever is used to make the brake pads engage.
A shifter is a lever, a lever is a simple machine
A sprocket is a lever.
Well, the lever will apply a force to a linkage, connecting the lever to the actual brake. Then the force will travel through the linkage, down to the brake. In the brake, the force will be used to pinch a moving surface between two stationary surfaces, and the friction generated there will slow the bike down.
It's the electronic hand-brake or parking brake lever.
yes
Pedal.
It has many parts that work together to preform a function. Just like other comples machinesIt's got wheels, axles, levers and gear ratios.Because it consists of many simple machines.A bicycle is built up of several simple machines, (the lever, wheel and axle etc), and several simple machines interacting becomes a compound machine.
