Concept explainers

Stress transformation

The term stress indicates the measure of internal forces that develop due to an external force's application on an object. When a specific external force is applied to an object, internal stress generates in the material. The value of stress can obtain by taking the ratio of the externally applied force and cross-sectional area of the object. There are different types of stress depending on the type of external force.

Q.2 (a) A hollow steel shaft of length 1.75 m transmits 2000 kW of power at a speed of 150 rev/min. The inside diameter is to be 0.75 times the outside diameter. The maximum allowable torsional shear stress for the steel is 130 MN/m and the modulus of rigidity (G) for the steel is 83 GN/m?. Given that a factor of safety of 2 is required for the shaft, determine: i) the torque acting on the shaft; ii) the required external and internal diameters for the shaft; ii) the torsional shear stress set-up in the shaft material at the inside surface of the hollow shaft, and sketch the stress distribution through the shaft wall; iv) the angle of twist (in degrees) due to the torque.

2.24 A rubber bearing pad under the steel girder above is used to produce a relatively uniform bearing stress on the concrete below. The literature from the pad manufacturer suggests that strain in the particular bearing pad should not exceed 12%. Due to the dead loading of the structure's weight, the pad is already strained by 3%. Say the live loads could produce an additional 0.25 in. of vertical motion of the girder, which must be tolerated. Determine the acceptable range of pad thicknesses that keeps strains below the maximum allowable strain. Prob. 2.24
