The doorstop depicted in Fig. 16-2a has the following dimensions: a = 6 in, b =4 in, c = 1.6 in, wy = 1 in, w2 = 0.8 in, where wz is the depth of the pad into the plane of the paper. (a) For a leftward relative movement of the floor, an actuating force F of 10 lbf, a coef- ficient of friction of 0.4, use a uniform pressure distribution pv. find Rr. Ry. Pav. and the largest pressure Pa- (b) Repeat part a for rightward relative movement of the floor.
