A part of the structure for a facory automation system is a beam that spans 30.0 inches as shown below. Loads that are applied at two points each 8.0inches from a support. The left load F1=1800 lb remains constantly applied while the right load F2=1800 lb is applied and removed frequently as the machine cycles. Find the following: Maximum stress Minimum stress Mean stress Alternating stress Stress ratio Solve the missing parameters in complete solution put necessary diagrams if needed. Thanks
