Mechanics of Deformables Spring 2007 Homework 8 Solution 8.1 The open-ended polyvinyl chloride pipe has an inner diameter of 4 in. and thickness of 0.2 in. It carries flowing water at 60 psi pressure. If the flow of water within the pipe is stopped due to the closing of a valve, determine the state of stress in the walls of the pipe. Neglect the weight of the water. Assume the supports only exert vertical forces on the pipe. 8.2 The open-ended pipe has a wall thickness of 2 mm and an internal diameter of 40 mm. Calculate the pressure that ice exerted on the interior wall of the pipe to cause it to burst in the manner shown. The maximum stress that the material can support at freezing temperatures is σ max = 360 MPa. Show the stress acting on a small element of material just before the pipe fails.

Unformatted text preview: 8.3 The joint is subjected to a force of 250 lb as shown. Determine the state of stress at points A and B, and sketch the results on differential elements located at these points. The member has a rectangular cross-sectional area of width 0.5 in. and thickness 0.75 in. 8.4 Determine the state of stress at point A when the beam is subjected to the cable force of 4 kN. Indicate the result as a differential volume element. Problem 8.4 and 8.5 8.5 Determine the state of stress at point B when the beam is subjected to the cable force of 4 kN. Indicate the result as a differential volume element. 8.6 The solid rod is subjected to the loading shown. Determine the state of stress at point C, and show the results on a differential volume element located at this point. Problem 8.6...
