two circular rods of 50mm diameter are connected by a knuckle joint as shown below, by a pin of 40mm in diameter. if a pull of 120KN acts at each end, find the tensile stress in the rod and shear stress in the pin.

A5 kg block of fe is dropped into a very large vat of water. the fe and water initial temperatures are 95 and 25 c, respectively. the fe final temperature is 25 c and the water can be treated as a thermal reservoir,. treated as a thermal reservoir take the water to be the system and determine the entropy generation. report vour answer in kj/k.
