In an upsetting process of a 304 Stainless Steel specimen of 200 mm in diameter and 150 mm height in an open die forging to a reduction of height 40%. If the
coefficient of friction is 0.2 and the yield strength of the material is 300 MPa,
Calculate the force required for the process at the end of the stroke.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

An electrical motor raises a 50kg load at a construct velencity .calculate the power of the motor, if it takes 40sec to raise the load through a height of 24m(take g =9.8n/g)

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false
