A simply supported beam is shown. The maximum bending moment is at B. Use the method of sections to determine the moment at B. Then determine the required section modulus needed for an allowable bending stress of 24 ksi. Verify that two L4x3 angles placed as shown will support the loading based on the angle thickness you select using Appendic C. Ans: MB = 4350 lb-ft %3D

It is defined as, two or more elements like beams or any two or more force members, which when assembled together, behaves like a complete structure or as a single structure. They generally consist of two force member which means any component structure …

If a body is said to be at rest or moving with a uniform velocity, the body is in equilibrium condition. This means that all the forces are balanced in the body. It can be understood with the help of Newton's first law of motion which states that the res…

When a body comes in interaction with other bodies, they exert various forces on each other. Any system is under the influence of some kind of force. For example, laptop kept on table exerts force on the table and table exerts equal force on it, hence th…
