Question

Chapter 11, Problem 037 A dump truck uses a hydraulic cylinder, as the drawing illustrates. When activated by the operator, a pump injects hydraulic oil into the cylinder at an absolute pressure of 1.30 x 10o6 Pa and drives the output plunger, which has a radius of 0.200 m. Assuming the plunger remains perpendicular to the floor of the load bed, find the torque that the plunger creates about the axis identified in the drawing. 50 m Output plunger Axis Load bed Input for hydraulic oil Number Units the tolerance is +/-296 LINK TO TEXT

Explanation / Answer

Here, Force = pressure*area = [1.3e6+101325]*pi*0.200^2 =176095 N

now, Torque = F*L = 176095*3.5 = 616332 Nm answer
