A square plate of mass $120 \mathrm{~g}$ and edge $5 \cdot 0 \mathrm{~cm}$ rotates about one of the edges. If it has a uniform angular acceleration of $0-2 \mathrm{rad} / \mathrm{s}^{2}$, what torque acts on the plate?
A square metal plate with mass M = 1.20 [kg] and side length 0.180 [m] is pivoted about an axis through point O at its center and perpendicular to the plate. Three forces of magnitude F1 = 18.0 [N], F2 = 26.0 [N], and F3 = 14.0 [N] act on the plate as shown. a. What is the net torque on the square plate due to these forces? b. What is the angular acceleration of the disk? The moment of inertia for a plate of length a and width b rotating about its center is Icom = 1/12 M(a^2 + b^2). c. If the plate is initially at rest, what is the angular velocity of the particle after 3.00 [s]?

A square metal plate 0.180 m on each side is pivoted about an axis through point O at its center and perpendicular to the plate (Figure 1). part a. Calculate the net torque about this axis due to the three forces shown in the figure if the magnitudes of the forces are F1 = 20.0 N, F2 = 14.9 N, and F3= 15.5 N. The plate and all forces are in the plane of the page. Take positive torques to be counterclockwise. Express your answer in newton-meters.
