The wedge blocks are used to hold the specimen in a tension testing machine. Determine the largest design angle ? of the wedges so that the specimen will not slip regardless of the applied load. The coefficients of static friction are ?_A = 0.1 at A and ?_B = 0.6 at B. Neglect the weight of the blocks.
