... The above condition is sufficient for a point-like object to be at its translational equilibrium. However for an object with size this is not sufficient. One more condition is needed. What is it? Let’s consider two forces equal in magnitude but in opposite direction acting on a rigid object as shown ...

... The switch on the plastic case lets you choose a 10-N or a 50-N range. Because the weight of the aluminum “C” is enough to change its shape, you will find that the force shown by the probe depends on its orientation. The shape also depends on temperature. To correct for these conditions, you must “z ...
