one kg of water vapor at 200 kPa fills the 1.1989 m^3 left chamber of a partitioned system. The right chamber has twice the volume of the left and is initially evacuated. determine the pressure of the water after the partition has been remived and enough heat has been transferred so that the temperature of the water is 3(degrees)C.
Two bars, one having a circular section of radius b, the other an elliptic section with semiaxes a,b. For equal angles of twist, which bar experiences the larger shearing stress?
What is the total force reaction (magnitude) at pin joint O when the square plate is released from rest? Assume the plate has a uniform thickness.
Use the bisection method to determine the drag coefficient (cd) needed so that a 80 kg bunjee jumper has a velocity of 36 m/s after 4 s of free fall.
