Take great care with the direction of rotation. A rigid body is said to be in equilibrium if; 1. the vector sum of the forces acting is zero ( the sum of the components in any direction is zero) 2. the algebraic …
WebTo determine the reactions at supports, follow these simple steps: 1. Let the sum of moments about a reaction point equal to ZERO (ΣM = 0) All we need to know about moments at this stage is that they are equal to the force multiplied by the distance from a point (i.e. the force x distance from a point). Consider a simple example of a 4m beam ... WebAug 28, 2024 · Sum of moments of components. M = ± F x d y ± F y d x Example 4.3.3. Verignon's theorem. A 750 lb force is applied to the frame as shown. Determine the moment this force makes about point A. Answer Solution The interactive diagram below will help you visualize the different tools to find moments that were covered in this section.
