Explain the support reaction? What are different types of support and their reactions?
Sol.: When the numbers of forces are acting on a body, and the body is supported on the other body, then the second body exerts a force known as reaction on the first body at the points of contact so that the first body is in equilibrium. The second body is called as support and the force exerted by the second body on first body is called as support reaction.
There are three types of support;
1. Roller support
2. Hinged Support
3. Fixed Support
Roller Support: Beams end is supported on the rollers. Reaction is at the right angle. Roller can be treated as frictionless. At the roller support only one vertical reaction
