The lever must exert a force of P = 2200 lbs at B as shown. The lever lengths are a = 8 in. and b = 41 in. The allowable bending stress for the lever is 12100 psi. If the lever height h is to be 3.0 times the lever thickness t (i.e., h/t = 3.0), what is the minimum thickness t that can be used for the lever? Use equilibrium to calculate the magnitude of load Q.

Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.
