A box is placed on the right hand side of a see saw, producing a -389 Nm torque (clockwise).
If a second box with weight 76 N is placed on the left hand side of the see saw, how far (radius) must it be placed from the pivot point so that the see saw is balanced, i.e. in equilibrium? Assume that the force of the box is applied perpendicular (theta = 90 degrees) to the see saw.
Hint: remember that for equilibrium, similar to linear forces, the net torque of the system must be equal to zero.
Net torque:
for equilibrium:
T+T2 = 0
