Question

A spur gear transmits 35 N middot m of torque to the 20-mm-diameter driveshaft. The 5-mm-diameter setscrew threads onto the gear's hub, and it is received in a small hole that is machined in the shaft. Determine the shear stress in the screw along the shear plane B-B A plastic pipe carries deionized water in a microelectronics clean room, and one end of it is capped (Figure P5.25). The water pressure is pQ = 50 psi, and the cap is attached to the end of the pipe by an adhesive. Calculate the shear stress r present in the adhesive. Structural steel and stainless steel are both primarily made of iron. Why doesn't stainless steel rust? Research the issue and prepare an approximately 250-word report describing the reason. Cite at least three references for your information. Recent technological advances have allowed for the production of graphene, which is a sheet of carbon atoms one atom thick, densely packed into a honeycomb structure. This material has excellent electrical, thermal,

Explanation / Answer

The formula to calculate average shear stress is[citation needed]: au = {F over A}, where: au = the shear stress; F = the force applied; A = the cross-sectional area of material with area parallel to the applied force vector.
