A beaker of fresh water is in place on the scale when the 1-lb stainless-steel cylinder is added to the beaker. What is the normal force which the cylinder exerts on the bottom of the beaker? By how much does the scale reading increase as the cylinder is added? Explain your answer.
In order to determine the properties ofa dense gas at high pressures, 10 lbm of the gas was heated at 4000 psia from 700 to 740°F. The gas volumes were 0.287 and 0.328 ft^3 in the initial and final states, respectively, and the required energy transf..

The 60-mm diameter shaft rotates at 300 rev/min. this motion is caused by the unequal belt tensions on the pully of 800 N and 450 N. Determine the power transmitted and the maximum shear stress developed in the shaft.
A piston-cylinder device holds 2 kg of refrigerant fluid R-134a, initially at 500 KPa. At this state, 0.5 kg of the fluid is in the liquid phase. Heat is then added to the fluid at constant pressure to increase its temperature to 60 c.
