Description

Quiz 1 -Home ----------A compound shaft with applied torques and dimensions is shown below. Section AB is made of steel. Section BC is made of brass. Section CD is made of steel. For this shaft: determine the maximum shear stress and the section in which it takes place. The modulus of rigidity for steel = 12×106 lb/in2. The modulus of rigidity for brass = 6×106 lb/in .

-----A circle of diameter d=9 in. is scribed on an unstressed aluminum plate of thickness t=3/4 in. Forces acting in the plane of the plate later cause normal stresses σxx = 12 ksi and σzz = 20 ksi. For E = 10x106 psi and Poisson's ratio = 1/3, determine the strain in the diameter AB

-----

The connection shown in the figure consists of five steel plates, each 2.5mm thick, to be joined by a single bolt. Determine the required diameter of the bolt if the allowable bearing stress, σb , is 180.0MPa and the allowable shear stress, τallowed , is 45.0MPa?...
