A heavy steel ball is resting in a trough as shown in the figure. The weight of the ball is 2300 N. Determine the reaction forces Ra and Rg developed at the contact surfaces A & B. The angle between Ra and Rs is Alpha (a) and the angle between Re and the weight W is Beta (B). One of the surfaces of the trough is at 90° and the other is inclined at an angle e, = 15° with the horizontal. Assume all contact surfaces are smooth.

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.
