Support conditions are external forces applied to a rigid body that cause it to deform or move from its original position. These forces can be categorized into two types: internal forces and external forces.
Internal forces are forces generated by the body itself, such as the force of tension in a rope or the force of compression in a spring. These forces act within the body and cannot be easily separated from the deformed shape.
External forces are forces applied to the body from the outside world, such as the force of gravity pulling an object down or the force of a wrench turning a bolt. These forces act on the body and can cause it to deform or move from its original position.
The study of support conditions is crucial in engineering mechanics as it helps engineers analyze the equilibrium of rigid bodies in various loading conditions. By understanding the relationship between the applied forces and the resulting deformation, engineers can predict the motion and behavior of structures and machines.
Here are some examples of support conditions:
Normal force: A force applied perpendicular to a surface, such as the force of a wall pushing a wall panel.
Shear force: A force applied parallel to a surface, such as the force of a wrench turning a bolt.
Moments: External forces applied about a certain axis, causing the body to rotate around that axis.
Hydrostatic force: The force exerted by a fluid on a submerged object, such as the force of water pushing a boat.
Understanding the concept of support conditions is essential for students studying engineering mechanics, as it forms the foundation for understanding how structures and machines behave under different loading conditions
