Q3: The cylinder shown in Fig. (2), Ayinder=7.012cm, has two pistons mounted, the upper one, mp1 =100kg, initially resting on the stops. The lower piston (m2 =0kg) has 2kg water below it, with a spring (linear) in vacuum connecting the two pistons. The spring force is zero when the lower piston stands at the bottom, and when the lower piston hits the stops the volume is 0.3m. The water, initially at 50kPa, V =0.00206m', is then heated to saturated vapor. Determine: (1) the initial temperature (2) the pressure that will lift the upper piston (3) The condition of steam when the lower piston hits the stops (4) the work done by the water (at saturated vapor state).
A torque of 2 N-m is necessary to rotate a paddle wheel at a rate of 20 rad/s.The paddle wheel is located in a rigid vessel containing a gas. What is the net work injoule done on the gas during 10 minutes of operation?
Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot. Hint: In the final stage, the temperature is 115°C, but the pressure is not given. You need to find P and v using the tables and P-v plot.
For masses and are 200 kg, 300 kg, 240 kg, and 260kg respectively.

Find the position and magnitude of the balance mass required, if it’s radius of rotation is 1.4 m.
A man is standing on a board on a frozen lake where there is no friction between the board and the ice surface. Tha man's mass is 2 m and the boaf's mass is 4 m. The board has length L. He walks from 1/5 Lfrom the left end of the board to 1/5 L from the right end of the board. How far and in which direction does the board move during this process?
A piston cylinder device contains B kg of water at A ° C. The frictionless piston with an area of C m2 initially rests on the stoppers and its cylinder volume is 0.03 m3. The pressure in the cylinder must be D kPa for the piston to activate. As the piston moves upwards, when the cylinder volume is 0.075 m3, it touches the linear spring with a spring coefficient of 360 kN/m. Since the final pressure is E MPa, by showing the state change together with the saturation curves on the P-V diagram, a) The water temperature in the last case,b) The work done during the transaction,c) Calculate the total heat transfer. Note: If you think there is missing data, you can choose appropriate values by making the necessary explanations.

To get up on the roof, a person (mass 66.7 kg) places an aluminum ladder (mass 9.30 kg) against the house on a concrete pad with the base of the ladder 2.27 m from the house. The ladder rests on a plastic rain gutter, which we can assume to be frictionless. The gutter is 6.96 m from the bottom of the ladder. The center of mass of the ladder is 2.32 m from the bottom. The person is standing 3.32 m from the bottom of the ladder. What are the magnitudes of the forces on the ladder at the top and bottom?
