The force applied at the handle of the rigid lever causes the lever to rotate clockwise about the pin B through an angle of 2 deg. Determine the average normal strain in each wire. The wires are unstretched when the lever is in the horizontal position shown. G F 200 mm 200 mm 300 mm -300 mm- E A B C D 200 mm H

The head H is connected to the cylinder of a compressor using six 316-in. diameter steel bolts. If the clamping force in each bolt is 800 lb, determine the normal strain in the bolts. If sY = 40 ksi and Est = 2911032 ksi, what is the strain in each bolt when the nut is unscrewed so that the clamping force is released?

Suppose that a= 420 mm and b= 560 mm Part A: Determine the average normal strain along diagonal BD Part B: Determine the average shear strain at corner B relative to the x, y axis

Draw Mohr’s circle for sx = sy = txy = 2 kPa. On the circle, label the axes and the principal stresses and their angles. Using three significant digits, determine the principal stresses and their angles, and the normal and shear stresses at q = 80 degree. The three gages from the strain rosette mounted on a steel shaft have the following readings: εa = 0.000316, εb = 0.000248, and εc = 0.000579. Determine the strain components: εx, εy, and Yxy.
