A force of P = 20 N is applied to the cable, which causes the 175-kg reel to turn without slipping on the two rollers A and B of the dispenser. Determine the angular velocity of the reel after it has made two revolutions starting from rest. Neglect the mass of the cable. Each roller can be considered as an 18-kg cylinder, having a radius of 0.1 m. The radius of gyration of the reel about its center axis is kg = 0.42 m. %3D

Amass of 3 kg of saturated liquid-vapor mixture of water is contained in a piston-cylinder device at 150 kpa. initially, 1 kg of the water is in the liquid phase and the rest is in the vapor phase. heat is now transferred to the water, and the piston, which is resting on a set of stops, starts moving when the pressure inside reaches 500 kpa. heat transfer continues until the total volume increases by 20 percent. determine (a)-the initial and final temperatures, (b)-the mass of liquid water when the piston first starts moving, and (c)-the work done during this process. d)-show the process on a p-v diagram. you don't need to indicate p& v values, but clearly indicate where all states are located in the phase diagram.
