1) (6pts) A light triangular plate OAB is in a horizontal plane. A force F1 = 8.0 N acts on the plate on point A, as shown. Another force F2 = 18.0 N acts on the plate at B, as shown and a third force F3 = 9.0 N acts on the plate at O, as shown a) What is the magnitude of the torque due to the force F1 with respect to the axis going through point O? b) What is the magnitude of the torque due to the force F2 with respect to the axis going through point O? c) What is the magnitude of the torque due to the force F3 with respect to the axis going through point O? d) If the moment of inertia around O is I = 0.5 kg.m², find the number of revolutions around O that the plate completes after 10s, assuming it starts at rest.

Step 1
It is calculated by multiplying the force applied to an object by the distance from the axis of rotation. The formula for torque is: Torque = Force x Distance Where: - Torque is measured in units of Newton-meters (Nm) Show more…
