Combined Normal Stresses FIGURE Shows a metal-cutting hacksaw. Its frame is made of hollow tubing having an outside diameter of 12 mm and a wall thickness of 1.0 mm. The blade is pulled taut by the wing nut so that a tensile force of 160 N is applied to the blade. Compute the maximum stress in the lop section of the tubular frame.
