1160_Newton's Laws and Static Equilibrium 2 Newton’s Laws and Static Equilibrium Isaac Newton 1643-1727 Recall Newton’s 2 nd Law in equation form: a F m = where is a force vector acting on a structure, is the mass of the structure, and is the resulting acceleration vector If 0 a 0 = a a F m You have a “dynamics” problem You have a “statics” problem, and the structure is said to be in static equilibrium. This is our arena of study in ENGRI 1160
1160_Newton's Laws and Static Equilibrium 3 Newton’s Laws and Static Equilibrium 0 = F Newton’s 3 rd Law states: Forces of action and reaction are equal in magnitude and opposite in direction. These two statements of physical law are our tools of
