FAQs on Simply Supported Beam - Problem Video Lecture - Strength of Materials (SOM) - Mechanical Engineering

1. What is a simply supported beam?
Ans. A simply supported beam is a type of beam that is supported at both ends with pins or rollers, allowing for vertical movement but not horizontal movement.
2. How do you calculate the reactions at the supports of a simply supported beam?
Ans. The reactions at the supports of a simply supported beam can be calculated by taking moments about one of the supports and solving for the unknown reactions.
3. What is the equation for the bending moment in a simply supported beam?
Ans. The equation for the bending moment in a simply supported beam can be calculated using the formula M = -wx^2/2 + R1x, where M is the bending moment, w is the distributed load, x is the distance from the support, and R1 is the reaction at one of the supports.
4. How do you determine the maximum deflection of a simply supported beam?
Ans. The maximum deflection of a simply supported beam can be determined using the equation δ = 5wL^4 / (384EI), where δ is the maximum deflection, w is the distributed load, L is the length of the beam, E is the modulus of elasticity, and I is the moment of inertia.
5. What are the typical applications of simply supported beams in engineering?
Ans. Simply supported beams are commonly used in structures such as bridges, buildings, and roofs, as they are easy to analyze and design for a variety of loading conditions.
