6. The rigid block A is supported by a shear spring and a block B. The shear spring is made of two polyethylene pads (E = 65 ksi, v = 0.5) with cross-sectional dimensions of 3 in x 4 in while block B is made of aluminum (E = 10 x 103 ksi, v = 0.25) with the dimensions as shown. Determine the weight of A if B expands along z by 0.01 in. Note that the expansion of B along the x- axis is hindered by the rigid walls. 1 in 1 in A AY B N 5 in B 2 in 3 in 6.
