Determine the diameter of the piston rod of the hydraulic cylinder of 100 mm bore when the maximum hydraulic pressure in the cylinder is limited to 11.6 N/mm2. The length of the piston rod is 1.2 m with a yield point value of 300 MPa. The factor of safety may be taken as 2.5 and the end fixity coefficient as 2. Express your answer in mm. Round your answer to 4 significant figures.

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.
