PRINTER VERSIONBACK NEXT Chapter 11, Problem 037 A dump truck uses a hydraulic cylinder, as the drawing lustrates. When activated by the operator, a pump injects hydraulic ol into the cylinder at an absolute pressure of 4.67 x 106 Pa and drives the output plunger, which has a radius of 0.190 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 Output plung Input for hydraulic oil Number Units the tolerance is +/-396

Explanation / Answer

Torque T = FL

But F = PA

So,

T = PAL

= (4.67*10^6)(pi*0.19^2)(3.50)

= 1.85*10^6 Nm
