Question

A bicycle rider would like to compare the effectiveness of candilever hand brakes (use figure a) versus V brakes (figure part b). (a) Calculate the braking force Rb at the wheel rim for each of the bicycle brake systems shown. Assume all forces are act in the plane of the figure and that cable compression T=45 lbs. Also, what is the average compressive normal stress (Sigma) on the break pad. (A= 0.625 in^2) (b) For each breaking system what is the stress in the brake cable. (assume effective cross-sectional area of 0.00167 in^2)
