Question 3 A caliper brake is required for the front wheels of a passenger car with a braking capacity of 500 Nm for each bra

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.

Answers

given Torque Capacity (I) = 500 Nm H=0.38 ri = 110 mm ☺ To = 200 mm (for Bugatti Chiron) 0 = 439 Nominal Diamald) = 25.4 mm P© Area of hydraulic Cylindes!. . A = 7x82 = ax (0.0127) 2 = 5.067 x104m2 Required hydraulic Pressuse!. Prud e f = 4844.482 N.

Hope this is helpful. Feel free to ask any doubt.
