The motorcycle specifications are given below. Find the time and distance required to decelerate from 100 k mph to a standstill at a deceleration of 10 m/s 2. Also, find the effort required to pull the lever and comment whether it is within ergonomic limits for an average human being. Assume that the rider applied the front brakes only. Find out rise in temperature of the front Disc. (Ignore Heat dissipation due to convection and radiation)

Motorcycle Weight (with rider): 260 kg

Front Tyre Size: 120/70 R 17

Number of Front Discs: 1

The coefficient of Friction (Brake Pad/Brake Disc): 0.5

Type of Caliper: Fixed Type - 4 piston

Caliper Piston diameter: 30 mm

Master Cylinder Diameter: 16 mm

Effective Diameter of Disc: 300 mm

For Brake Lever:

Piston to Fulcrum: 40 mm

The angle between links at the fulcrum: 90 degrees.

Fulcrum to Force Application Point: 150 mm

Specific Heat Capacity of Disc material = 460 J/Kg.K

Mass of front Disc = 1.5 kg
