Video Problem #1, Lecture #9: A 1.6m board is centered on a pivot as shown in the figure. One rope pulls straight up with a tension of 300 N and the other rope pulls at an angle of 30 degrees from the horizontal with a force of 400 N. Calculate the magnitude of the combined torque on the board about the pivot point due to the two ropes.
