Calculate the net torque about point 0 for the two forces applied as in the figure below. The rod and both forces are in the plane of the page. Let F, = 7.90 N and F, = 10.0 N. Take counterclockwise torques to be positive. F2 30.0 K-2.00 m-* 3.00 m

The answers are provided; please explain the purpose of each equation and why they were used Consider a bar of length 5.5 m, being acted on by three forces and constrained to rotate about its left end. The magnitudes of the first two forces are 19 N and 28 N and the first force is acting on the end of the bar at an angle of 43° What is the torque in newton-meters, due to F1 on this bar relative to the left end?   Ans. = 78.87 Nm Equation used: τ1 = rFsinθ   What is the torque in newton-meters, due to F2 on this bar relative to the left end, if this force is acting at the midpoint of the bar? Use a coordinate system with positive directed out of the screen. Ans. = 77 Nm Equation used: τ2 = F2 x (L / 2)   What is the magnitude of the force F3, in newtons, if the force is a distance 0.85 m from the left end and the bar is not rotating?  Ans. = 183.38 N  Equation used: F = (τ1 + τ2) / d
