See all →- What are the conditions of equilibrium for concurrent forces and how is Lami's theorem used? In one line Concurrent coplanar forces are in equilibrium when the sums of their x and y components are both zero; for exactly three such fo... 1
- What are the conditions of equilibrium for parallel and general coplanar forces, and how are couples balanced? In one line A body under parallel or general coplanar forces is in equilibrium only when the net force is zero and the net moment about ever... 1
- What is a free body diagram and how do you draw it correctly for equilibrium problems? In one line A free body diagram (FBD) is a sketch of the body cut free from its surroundings, showing every external force and reaction acti... 1
- What are two-force and three-force bodies and how do they simplify rigid body equilibrium? In one line A rigid body in equilibrium under only two forces needs them equal, opposite and collinear; under three non-parallel forces, the... 1
- What are the types of beams, and what is the difference between a simple and a compound beam? In one line Beams are classified by their supports into simply supported, cantilever, overhanging, fixed, propped cantilever and continuous;... 1
- What are the types of supports on beams and what reactions does each provide? In one line A support provides a reaction for every motion it stops: a roller gives one force, a hinge gives two forces, and a fixed support... 1
