A uniform disk with mass m = 9.24 kg and radius R = 1.41 m lies in the x-y plane and centered at the origin. Three forces act in the +y-direction on the disk: 1) a force 339 N at the edge of the disk on the +x-axis, 2) a force 339 N at the edge of the disk on the -y-axis, and 3) a force 339 N acts at the edge of the disk at an angle θ = 38° above the -x-axis.

1) What is the magnitude of the torque on the disk about the z axis due to F₁? 

2) What is the magnitude of the torque on the disk about the z axis due to F₂? 

3) What is the magnitude of the torque on the disk about the z axis due to F₃? 

4) What is the x-component of the net torque about the z axis on the disk?
