###### Question:

Question 3 A caliper brake is required for the front wheels of a passenger car with a braking capacity of 500 Nm for each brake. Preliminary design estimates have set the brake geometry as n = 110 mm' and 8 = 43º. Pads with a coefficient of friction of 0.38 have been selected. Each pad is actuated by means of a hydraulic cylinder of nominal diameter 25.4 mm. Determine: 3.1 3.2 3.3 the required actuating force, the average and the maximum contact pressures, the required hydraulic pressure for brake actuation. [10] The student is to take the outer radius of the brake to be that of the Bugatti Chiron.
