Question
PVC plastic is often used for sewer pipe. If the outerdiameter of any pie ranges from 4 in.<= x<= 8 in, design atool that can be used by a worker to turn the pipe when it issubjected to a maximum anticipated ground resistance of 80 Ib-ft.The device is to be made of steel and should be designed so that itdoes not cut into the pipe and leave any significant marks on itssurface. Assume a worker can apply a maximum (comfortable) force of40 Ib, and take the minimum coefficient of static friction betweenthe PVC and the steel to be s = 0.35. Submit ascaled drawing of the device, and a brief paragraph to explain howit works based on a force analysis.Explanation / Answer
It would effect by torsion and force an apllied moment on the pipe.
