A support is an external element that resists the applied shear force or bending moment in a structure. There are three primary types of supports:
1. Fixed Supports:
These supports act like a fixed wall, preventing the structure from moving or rotating.
Examples: Walls, pillars, and foundations.
2. Pin Supports:
These supports resemble a hinge, allowing the structure to rotate around a single point.
Examples: Joints, hinges, and connections in mechanical components.
3. Cleat Supports:
These supports resemble a smooth, curved surface that allows the structure to deform continuously.
Examples: Rubber pads, rubber mounts, and flexible beams.
Each type of support has its own unique characteristics and limitations. The type of support chosen depends on the desired behavior of the structure and the applied load.
Understanding Shear Force and Bending Moment:
Shear force is the force applied to a structure perpendicular to a specific plane.
Bending moment is the moment about a specific axis that measures the tendency of a structure to bend.
Knowing the types of supports and the behavior of shear force and bending moment is crucial for engineers and structural designers to analyze and select appropriate solutions for various structural applications
