Disc Brakes:
Disc brakes consist of two parts: a rotor attached to the hub and a caliper. The caliper is attached to the frame of the bicycle when fixed at the rear end or fork when fixed to the front end. Two brake pads are mounted into the caliper. The pads are squeezed against the rotor when the user presses the brake handles located at the steering arms (Annan, James). Disc brakes are used in trucks, cars and motorcycles since a long time. Nowadays, they are becoming available for road bicycles with continual reduction in weight due to advance in materials. Many bicycles have a disc brake on the rear wheel in addition to rim brakes; the disc brake can be set to provide a constant braking force or drag for mountain descents. Disc brakes are more useful when compared to regular rim brakes for steep and wet grounds. In our case, the Tricylce weighs around 160 Kg thus, requiring larger stopping forces which could be provided only by disc brakes (See following figure)
Brakes' Calculation
The force applied by the user on the brake handle was evaluated to be equal to 20 N which will increase to be equal to 295 N applied on the caliper.
Thus the calculated stoppage time was equal to 5 seconds
