A flange of radius 200mm is fastened to the machine screw by means of four cap screws of pitch circle radius 150mm. The external force P is 20kN which is loaded at 160mm from the machine screw. There are two dowel pins to take shear load. Determine the core diameter of cap screw if permissible tensile stress in cap screw is 40N/mm².

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
