Basically: The equilibrium equations for rigid bodies are a way to determine unknown forces and moments using known forces and moments, separating the motion in 2 (or 3) directions for translation and rotation. Moments could be calculated because rigid bodies also consider shape and length.

WebIn a truss, a zero force member is often found at pins (any connections within the truss) where no external load is applied, and three or fewer truss members meet. Identification of basic zero force members can be accomplished by analyzing the forces acting on an individual pin in a physical system. If the pin has an external force or moment ... WebJul 28, 2024 · the sum of the moments must be equal to zero. In order to have the sum of the forces equal to zero, the force vector on the other side of the beam must be equal in magnitude and opposite in direction. This is the only way to ensure that the sum of the forces is equal to zero with only two forces.
