| dc.description | Notions of force, torque and mechanical equilibrium | |
| dc.description | A rigid bar of negligible mass is supported on either end by two triangular blocks. On top of the bar sits a box of variable mass that can be moved along the bar. The sum of the forces in the x or y direction, Fx and Fy, must be zero. In the direction y this means that the force exerted by the block on the bar, Fa, must be balanced by the forces from the triangular blocks on the bar, Fb and Fc; therefore Fa=Fb+Fc, or Fb=Fa-Fc. There are no forces acting in the x direction.
The sum of the counterclockwise torques must equal the sum of the clockwise torques | |
