An acetal polymer block is fixed to the rigid plates at its top
and bottom surfaces.
If the top plate displaces 2
mm horizontally when it is
subjected to a horizontal force P = 2.3kN
, determine the shear modulus of the polymer. The width of the
block is 100 mm. Assume that the
polymer is linearly elastic and use small angle analysis.
Express your answer to three
significant figures and include the appropriate units.

The pin-connected structure shown in Fig. 5 consists of a rigid bar ABCD and two 1,500-mm-long bars. Bar (1) is steel [E=200 GPa] with a cross-sectional area of A1 = 510 mm2. Bar (2) is an aluminium alloy [E-70 GPa] with a cross-sectional area of A2 1,300 mm2. All bars are unstressed before the load P is applied. If a concentrated load of P 200 kN acts on the structure at D determine: (a) the normal stresses in both bars...
