The capacity of a passenger elevator is 2, 500 pounds. This load is supported by a 2-inch diameter steel cable (E=200GPa, v=0.33, sigma_y = 500MPa). What percentage of the yield strength of cable is used by the maximum load? What is the axial strain along the cable? What is the new diameter of the cable at maximum load? What do you think of the design of this elevator? A state of stress in a thin plate is given by: sigma_11 = 110MPa sigma_22 = 200MPa sigma_12 = 45MPa Write down the corresponding stress tensor for this frame of reference. Determine the principal stresses and the maximum shear stress, as well as their
