... At the equilibrium position, the net torque acting on the loop is zero. Choosing rotational axis along the hinged side, we have Στ = 0 ⇒ NIBL²cosθ-mg(L/2)sinθ = 0 ⇒ tanθ = 2NIBL/(mg) = 2×50×3×0.05×0.2/(0.4×9.8) = 0.765 ⇒ θ = tan-1(0.765) = 37.4˚, where θ is the angle between the vertical and the pla ...
