The magnitude of F₂ has to be for there to be a rotational equilibrium will be 3 N.
If the rotational velocity of an item is constant, it is said to be in rotational equilibrium. An item in rotational equilibrium is one that is neither spinning nor is rotating at a steady pace in one direction.
The net torque operating on the item must be zero in order for it to be in rotational equilibrium.
[tex]\rm 12 \times0- F_2 \times 4 +0 \times 4 \\\\\ \rm F_2 = 3 N[/tex]
Hence the magnitude of F₂ has to be for there to be a rotational equilibrium will be 3 N.
