A uniform disk with mass m = 9.27 kg and radius R = 1.42 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 343 N at the edge of the disk on the +x-axis,
2) a force 343 N at the edge of the disk on the -y-axis, and
3) a force 343 N acts at the edge of the disk at an angle ? = 39° above the -x-axis.
a) What is the magnitude of the torque on the disk about the z axis due to F1?
A box weighing 900 N rests on a surface. A force of 500 N is pushing on the side of the box. find The magnitude of static friction acting on the box
Water flows straight down from an open faucet. The cross-sectional area of the faucet is 2.00 x10-4 m2, and the speed of the water is 0.87m/s as it leaves the faucet.
A 46kg box is being pushed a distance of 7 m across the floor by the force vector P whose magnitude is 144N. The force vector P is parallel to the displacement of the box.
