1. 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 =9 N, F₁₂ =4 N, F₁ =7 N. Assume all quantities are correct to 3 significant figures. Assume the positive z-axis is out of the page. Think & Prepare 1. 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. 2. Which forces produce clockwise rotations and which forces produce counter-clockwise rotations? 3. While using the formula for cross-product A XB =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. Enter to 3 significant figures Please include the sign of the torque. 7 net = 30° Nm k Ул F₂ 2 m 3 m F₁ FR O 2 m Fa 20%
