A strain gage is installed in the longitudinal direction on the surface of an aluminum beverage can (see figure). The radius-to-thickness ratio of the can is 190. When the lid of the can is popped open, the strain changes by 191 x 10-6. (Assume that the given radius or diameter is an inside dimension and that all internal pressures are gage pressures. Assume E = 10 x 106 psi and v = 0.33.) (a) What was the internal pressure p in the can (in psi)? psi (b) What is the change in strain in the radial direction when the lid is opened?

Your answer is incorrect. An extruded polymer beam is subjected to a bending moment M. The length of the beam is L = 500 mm. The cross-sectional dimensions of the beam areb1 = 35 mm, d1= 115 mm, b2= 21 mm, d2 = 21 mm, and a =7 mm. For this material, the allowable tensile bending stress is 15 MPa, and the allowable compressive bending stress is 14 MPa. Determine the largest moment M that can be %3D %3D %3D %3D %3D %3D applied as shown to the beam. b2 a 不 d2 d1 b1 Answer: N-m M% =

A strain gage is installed in the longitudinal direction on the surface of an aluminum beverage can (see figure). The radius-to-thickness ratio of the can is 200. When the lid of the can is popped open, the strain changes by εo = 170 x 10-6. What was the internal pressure p in the can? (Assume E = 10 x 106 psi and μ= 0.33.).
The solid circular drill rod AB is made of a steel that is assumed to be elastoplastic with τY = 22 ksi and G = 11.2 × 106 psi. Knowing that a torque T = 72 kip·in. is applied to the rod and then removed, determine the maximum residual shearing stress in the rod. The maximum residual shearing stress in the rod is ksi.
