Question

The rod ABCD is made of an aluminum alloy with a modulus of elasticity E = 70 GPa


The rod ABCD is made of an aluminum alloy with a modulus of elasticity E = 70 GPa. For the loading shown, and neglecting the weight of the rod, determine the stress in sections AB, BC, and CD and the deflection of point D. For stress, answer to nearest whole number. Use 3 decimal places for displacement. Drawing is not to scale. Assume compressive stresses are positive, and that displacement to the right is positive.
