If the top plate displaces 2 horizontally when it is subjected to a horizontal force PPP = 2.7 kNkN , determine the shear modulus of the polymer. The width of the block is 100 . Assume that the polymer is linearly elastic and use small angle analysis.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
