Drawings 1 and 2 of Figure P10.30 are identical except for placement of the spring washer. The bolt and the clamped members are "infinitely" rigid in comparison with the spring washer. In each case the bolt is initially tightened to a force of 10,000 N before the two 1000-N loads are applied.
(a) For both arrangements draw block A as a free body in equilibrium.
(b) For both arrangements draw a bolt-force-versus-time plot for the case involving repeated application and removal of the 1000-N external loads.
