The gauge pressure of a pneumatic cylinder reads 40 lb/in. 2 when the volume is 60 in. 3 . The cylinder is compressed until the gauge reads 120 lb/in. 2 . Assume standard atmospheric pressure (14.7 psi). a. What is the absolute pressure before and after the cylinder gas is compressed

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

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
