Statics internal forces

WebNov 5, 2024 · Statics is the study of forces in equilibrium. Recall that Newton’s second law states: (8.4.1) ∑ F = m a Therefore, for all objects moving at constant velocity (including a velocity of 0 — stationary objects), the net external force is zero. There are forces acting, but they are balanced — that is to say, they are “in equilibrium. ” WebMar 5, 2024 · A determinate structure is one whose unknown external reaction or internal members can be determined using only the conditions of equilibrium. An indeterminate structure is one whose unknown forces cannot be determined by the conditions of static equilibrium alone and will require, in addition, a consideration of the compatibility …
