Unformatted text preview: 74 W 310 74 Beams with Axial Loads When solving the problems for Section 5.12, assume that the bending moments are not affected by the presence of lateral deflections. Problem 5.12-1 While drilling a hole with a brace and bit, you exert a downward force on the handle of the brace (see figure). The diameter of the crank arm is and its lateral offset is Determine the maximum tensile and compressive stresses and , respectively, in the crank. s c s t b 4-7/8 in. d 7/16 in.
