A piston-cylinder assembly contains 3 kg of water, initially at 0.06 bar and 160 C. The water undergoes two processes in series:
D a constant volume process to saturated vapor followed by a cooling process. At the end of the cooling process, the temperature is 20 C and the water is a liquid-vapor mixture with a quality of 25%. Neglect kinetic and potential energy effects. i. (12) Determine the specific volume and specific internal energy of the water at a the initial state, b. the state at the end of the constant volume process, and li. (4) Sketch the T-v and p-v diagrams showing the key states, the ili (6) Find the work and heat transfer for the constant volume process, both in iv. (3) If 5500 KJ of heat is removed from the system during the cooling, c. the state at the end of the cooling process. processes, and relevant isobars or isotherms, kJ, calculate the work and comment whether this work is done on the system or by the system.

Answer:
This doesn't represent an equilibrium state of stress
Explanation:
∝ = 1 , β = 1 , y = 1
x = 0 , y = 0 , z = 0 ( body forces given as 0 )
Attached is the detailed solution is and also the conditions for equilibrium
for a stress state to be equilibrium all three conditions has to meet the equilibrum condition as explained in the attached solution
Answer:
a) Under damped
Explanation:
Given that system is critically damped .And we have to find out the condition when gain is increased.
As we know that damping ratio given as follows
Where C is the damping coefficient and Cc is the critical damping coefficient.
So from above we can say that
From above relationship we can say when gain (K) is increases then system will become under damped system.
