Mechanics of Solids

It is the study of the behavior of solid materials, their characteristics under various circumstances such as variation in external forces, temperature, and other internal factors. It is one of most important study in the field of engineering science, especially chemistry and mechanical engineering. In rigid body, the idealization of the solid body in which deformation is neglected. Deformation is known as the force acting on the solid state system which exerts change in its shape of the body but it continues to be at rest or in a uniform motion but it cannot accelerate. But those solid systems do have elasticity, compressibility and can be bent. This field is very vast since there are wide range of materials around us.

Question

Prob. 4.3-10. The solid circular shaft of diameter d in Fig.
P4.3-10a has a maximum shear stress Tmax = T under the action
of a torque T. If the solid shaft is replaced by a tubular shaft
with a ratio of outside diameter to inside diameter
of d/d; = 1.2 but weighing the same as the solid shaft
(Fig. P4.3-10b), by what percentage would the torque have to be
increased in order to produce the same maximum shear stress?
