- I need help filling out the table of which forces are being applied, the y, and the torque1. Calculate the torque about the z-axis pointing out of the page at the origin in the following figure given that F₁ = 2 N, F₂=9N, F3=4 N, F₁=5 N. Hint: Use the sign convention for torques, counter-clockwise rotation corresponds to a torque in the positive z-direction and clockwise rotation corresponds to a torque in the negative z-direction. Which forces produce clockwise rotations and which forces produce counter-clockwise rotations? While using the formula for cross-product AXB=ABsine, remember that is the angle between the tails of the vectors A and B. To determine e rearrange the vectors so that their tails coincide.
