Hydraulics & Pneumatics Test Questions

Q.  How is tilting action possible in trucks for unloading the gravel material using hydraulic power? 1. Tilting action is possible if, oil flows at high pressure into the cylinder 2. Tilting action is possible if, air flows at low pressure into the cylinder 3. The truck body tilts when piston rod in the actuator is pushed out. 4. Tilting action is possible if air is compressed at high pressure

a. 1 and 3
b. 2 and 4
c. 3 and 4
d. none of the above
