The motor draws in the cable at c with a constant velocity of vc= 4 m/s. The moto draws in the cable at D with a constant acceleration of aD=8 m/s^2. If vD=0 when t=0, determine: a) the time needed for block A to rise 3 m b)the relative velocity of block A with respect to block B when this occurs.

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.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
