Three point bending- three forces act on a structure produce 2 equal moments, each being the product of one of the two peripheral forces and the distance to the axis of rotation (the point at which the middle force is applied. If loading continues to yield point assuming the structure is homogenous and symmetrical, it will break at the point of application of the middle force. Fracture begins on the tension side in adult bone as bone is weaker in tension than compression. Examples include skiboot fractures of the tibia. In immature bone it may fail by compression causing buckling on the compression side
