Shear: 2b The steel bar shown above (problem Shear 10) (E = 200 GPa, a =11x10 4 /° C) is of rectangular cross-section (4cm x 10cm) and is to be bolted on a structure by 10 bolts on each side; the diameter of each is 3.5cm. Due to an error, the length L shown was 1.795 m instead of1.80 m, thus there is a gap of 0.5 cm, which makes it difficult to bolt the bar on the structure. The engineer suggests the bar is heated up by -AT in order to close the gap. (a) Find the AT required to close the gap. After the gap is closed and the bar is bolted, the bar is brought back to its original temperature. (b) Find the shear stress on each bolt. (c) Find the bearing stress on the bar.
