Mechanical equilibrium. For a mechanical system at equilibrium,the net force and the net moment of force (torque) are zero. Here two spring scales,a wooden ruler and a 50 g weight are used to demonstrate that. When the weight is positioned in the middle of the ruler,the scales' readings are the same. When the weight is moved toward one scale (this image),its reading is increased while the other scale's reading is decreased | |
