A wall bracket is attached to the wall by means of 2 identical bolts, one at A and one at B. The force of 20kN acts at a distance of 400mm. Bolt A lies at a distance of 50mm from axis of tilt and bolt B 500mm. Allowable shear stress in the bolts is 100N/mm² and tensile is 40N/mm². Which bolt is used a criterion for designing?

Threaded Joints in Machine Design topics include: Screws, screw jack, threaded joints, uniform bolt strength, and loads based on the principle of eccentricity. Threaded joints are mechanical joints that use threaded fastenings to hold machine parts together. They are also known as separable joints because they can be disassembled without damaging the parts.  Here are some types of threaded joints: Direct threads: Use direct screws to attach the component pieces. Indirect threads: Use standardized components like bolts, screws, and nuts to hold the component pieces. Acme thread: A... Show more
