Acaliper 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 ri = 110 mm1 and θ = 43°. 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: a)- the required actuating force, b)- the average and the maximum contact pressures, c)- the required hydraulic pressure for brake actuation. take the outer radius of the brake to be that of the bugatti chiron.
