17-28: The assembly has a mass of 8 g and is hoisted using the boom and pulley system. If the winch at B draws in the cable with an acceleration of 2 m/s 2 , determine the compressive force in the hydraulic cylinder needed to support the boom. The boom has a mass of 2 g and mass center at G.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
