Friction always opposes the motion and reduces the speed at which the object moves on the surface. Surfaces that are not level require the worker to compensate by placing the body in an awkward posture. In addition, from a stooped posture the worker must lift the weight of the torso up as the object is lifted. Therefore, in the proposed rule OSHA has taken the ergonomic risk factors and the combination of risk factors most associated with the occurrence of MSDs and tried to present them in ways that those with more limited knowledge about ergonomics can readily identify. Carrying boxes of metal scraps down steps. Structural vs. Cyclical Unemployment: What's the Difference. Child 2, moving at 10m/s, slides into child 1, moving at 2m/s. It does this by converting kinetic energy into heat or another form of energy.
