A wrench of length X cm is used to loosen a nut attached to a bolt. If a perpendicular force F Newtons is applied to the wrench, arrange in order of maximum to minimum, the torque that can be applied on the nut. Maximum 1 F(X-4)/100 Nm 2 F(X-2)/100 Nm 3 ⠀⠀FX/100 Nm + 4 F(X-X)/100 Nm Minimum

A carpenter is driving a nail straight into the northern wall of the house, with an average force of 1200 N. Find the magnitude of the torque of this force about a point on the wall 3.0 m to the right of the nail.

A force F=(-5j+3k)N is applied to an object that is a distance r=(2j+6k)m from a pivot point.  (a) Calculate the torque on the object.(b) Calculate the angle between r and F.

You stepped on the edge of a bicycle wheel (radius 0.622 m) to make it slow down. If you pressed with your foot with a force of magnitude 10.0 N directed towards the center of the wheel, and the coefficient of friction between the wheel and your shoe is 0.462, what is the magnitude of the torque due to the friction?

A thin cord is wrapped around a uniform grindstone of radius 0.30 m and mass of 25 kg supported by bearings that produce negligible friction torque. The cord exerts a steady tension force on the grindstone, causing it to accelerate from rest to 60 rad/s in 12 s. (lgrindstone = 5 What is the magnitude of the tension force of the cord? O 5.6 N 11.3 N O 18.7 N O 37.5 N

When opening a door, you push on it perpendicularly with a force of 67.5 N at a distance of 0.775 m from the hinges. What torque, in newton meters, are you exerting relative to the hinges?

Force F = (-7.0 N)î + (5.0 N) ĵ acts on a particle with position vector7 = (4.0 m)î + (5.0 m) ĵ. (a) What is the torque on the particle about the origin, in unit-vector notation? = N: m (b) What is the angle between the directions of r and Torque is the cross product of a position vector (extending from a chosen point, here the origin, to the particle) and a force vector. Did you take the cross product in unit-vector notation? Do you remember how find the angle between two vectors by taking a dot product in both unit-vector notation and also in magnitude-angle notation? (You can similarly use a cross product to do this.) Do you remember how to find the magnitude of a vector from its components?

Given the picture attached: (a) Find the magnitude of the net torque on an axis about C perpendicular to the page. (b) Is this clockwise or counterclockwise?

A capstan is a device used on old sailing ships to raise the anchor. A sailor pushes the long lever, turning the capstan and winding up the anchor rope. If the capstan turns at a constant speed, the net torque on it, is zero. The rope tension due to the weight of the anchor is 1500 N. The distance from the axis to the point on the lever where the sailor pushes is seven times the radius of the capstan around which the rope is wound.With what force must the sailor push in order to turn the capstan at a constant speed, meaning that the net torque on the capstan is zero?

A uniform disk with mass m = 8.75 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 315 N at the edge of the disk on the +x-axis, 2) a force 315 N at the edge of the disk on the -y-axis, and 3) a force 315 N acts at the edge of the disk at an angle 0 = 38° above the -x-axis. +y +x F3 IF, F2
