HW 6 Problems: 1. Using F = 2.2 kN, design the lever arm CD for the figure, below. Note: CD is the rod connected to the force and is in pure bending. 50 mm 300 mm 40-mm D. 3-mm R. 25-mm D. 380 mm 40-mm D. D' a. First, select your material. b. Second, assume a design factor of na = 1. c. Compute the diameter of the arm using distortion energy (DE) theory (for ductile materials). Note DE theory will use only the normal stress defined as o = d. Select a preferred size (Table A-17) to decrease the cost of the device. e. Compute the factor of safety. so = -my/I.
