Consider the square plate ABCD shown in the figure to the right whose rotation is about an axis through its center at point O and perpendicular to the plate. The forces are applied at different points on the plate: F- 10.0 N is applied at point B, F2- 7.50 N is applied at point D and Fs-9.00 N is applied at the midpoint between the side BC. (a) Calculate the magnitude the torque due to each force. (b) Determine the magnitude and direction (in terms of rotation) of the net torque on the rhombic plate. (c) lf a fourth force is to be applied at point A, what must be the magnitude and direction of that force such that it is minimum and that the plate attains rotational equilibrium?

Question
Consider the square plate ABCD shown in the figure to the right whose rotation is about an axis through its center at point O and perpendicular to the plate. The forces are applied at different points on the plate: Fi - 10.0 N is applied at point B, F: - 7.50 Nis applied at point D and Fs-9.00 N is applied at the midpoint between the side BC. (a) Calculate the magnitude the torque due to each force. (b) Determine the magnitude and direction (in terms of rotation) of the net torque on the rhombic plate. (c) lf a fourth force is to be applied at point A, what must be the magnitude and direction of that force such that it is minimum and that the plate attains rotational equilibrium? 143.1 30 cm
