Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Themaximum allowable torsional shear stress for the steel is 130 MN/m2and themodulus of rigidity (G) for the steel is 83 GN/m2. Given that a factor of safety of2 is required for the shaft, determine:i) the torque acting on the shaft;ii) the required external and internal diameters for the shaft; iii) the torsional shear stress set-up in the shaft material at the inside surfaceof the hollow shaft, and sketch the stress distribution through the shaftwall;iv) the angle of twist (in degrees) due to the torque.
