In these experiments, the beam was in rotational equilibrium once the "balancing mass" was placed in the required location. Was the beam also in translational equilibrium? Explain how you know based on what you observed in the experiment.

The beam was also in translational equilibrium. This means that the sum of all the forces acting on the beam was zero. One can see this because the beam was not accelerating up or down.

What is the experiments

To be in translational equilibrium, the sum of all the forces acting on an object must be zero. In the case of the beam, the only forces acting on it were the weight of the beam and the weight of the balancing mass. Since the beam was not accelerating, we know that the sum of these forces must have been zero.

So, one can also see that the beam was in translational equilibrium by looking at the torques acting on it. Torque is a force that causes an object to rotate. The sum of all the torques acting on an object must also be zero for the object to be in rotational equilibrium.
