In a beam balance, when the beam is balanced in a horizontal position, it is in ______.

Solution

The net torque acting on a beam balance in the balanced horizontal state is equal to zero. Thus, it is said to be in rotational equilibrium. Also, since the balance is at rest, the net force acting on it is zero, which makes it in static equilibrium too.
