The bell crank is in equilibrium for the forces acting in rods (1) and (2). The bell crank is supported by a pin with a diameter of 14 mm at B that acts in single shear. The thickness of the bell crank is 7 mm. Assume a = 60 mm, b= 100 mm, F₁ = 1000 N, and 9 = 75°. Determine the average shear stress in pin B. Answer in MPa rounded-off to 2 decimal places.

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.
