a) If the rod undergoes a temperature drop of 24°C, and the bolt at B is tightened causing the rod to elongate by 0.0566 mm, determine i. the average normal stress in the steel rod. ii. the average shear stress in the bolt. iii. the bearing stress between the bolt and the clevis.
A 1 meter long steel rod AB of 15-mm diameter is held snugly (without any initial stresses) between rigid walls by the arrangement shown in the figure. (For the steel rod, use E = 200 GPa , α= 12 x 10-6/°C , and yield strength σY = 250 MPa.)
a) If the rod undergoes a temperature drop of 24°C, and the bolt at B is tightened causing the rod to elongate by 0.0566 mm, determine
i. the average normal stress in the steel rod.
ii. the average shear stress in the bolt.
iii. the bearing stress between the bolt and the clevis.
iv. the bearing stress between the washer and the wall.
b) Determine the amount of temperature drop that is allowed if the factor of safety against yielding
is 4.
