Question:

A bicycle stem is shown in Figure P11-26. The stem attaches the handlebars to the steerer tube of the fork. The stem is made of 7075-T6 aluminum alloy with yield strength of 504 MPa. The load of 1200 N is spread over the mounting surface to the handlebar in the x - y plane and acts at a 45o angle from the axis of the stem. The inner surface of the stem that attaches to the steerer tube is fixed in translation in the y-direction and in rotation about the y-axis. Determine the largest von Mises stress and its location on the stem. (This problem is courtesy of Stephen Wilson.)
