2-B- The steel tube (E=200 GPa) with a 30 the vise on the tube at A and D. (b) The mm outer diameter and a 3-mm thickness is change in length of the portion BC of the tube. placed in a vise. That is adjusted so that its jaws just touch the ends of the tube without exerting any pressure on them. The two forces shown are then applied to the tube. After these forces are applied, the vise is adjusted to decrease the distance between its jaws by 0.2mm. Determine (a) the forces exerted by

A force stretches a wire by 4.0 mm. A third wire of the same material has the same length and twice the diameter as the first. How far will it be stretched by the same force?     4.0 mm     16 mm     8.0 mm     1.0 mm     2.0 mm
