1. A single horizontal force of 150 Ibf is applied to the end of lever ABC at C. AB has a diameter of1.2 inches and BC has a diameter of

0.75 inches. Determine the normal and shear stresses on an element located at point Q and having sidesparallel to the x and y axes. Draw an stress cube and show all applicable stresses on the positive faces. Label your axes. Determine the principal stresses and maximum shear stress and principal and shear planes. d. Sketch Mohr's circle for part C.
