Torque Physics: Lever Arm and Force

 Model the propeller of an airplane as a single thin rod, 2.2 m long, with a mass of 80 kg. How much torque is required to bring this propeller from rest to 600 rpm in 2.9 s? 

Physics, Torque (1 of 13) An Explanation

Torque of fish pulling on pole

A metal bar is in the xy-plane with one end of the bar at the origin. A force F = 97.00 N)i + (-3.00 N)j is applied to the bar at the point x = 3.00 m, y = 4.00 m. (b) What are the magnitude and direction of the torque with respect to the origin produced by F?

 Some trainyards have very large horizontal disks that engines can drive onto, which then rotate to turn the engine around to face the opposite direction. Suppose the train engine is 12 m long and centered at the disk’s axis. A 500 N force is applied 5.0 m from the center of the engine, with a rope that makes a <math display=“inline”><mrow><mn>35</mn><mo>&#x00B0;</mo></mrow></math> angle with the side of the engine. What magnitude torque is being applied to the train engine?

Torque, Basic Introduction, Lever Arm, Moment of Force, Simple Machines & Mechanical Advantage

<p>You pull with a 100 N at the edge of a 25 cm long wrench, to tighten a bolt (gold), as shown. The angle shown is 53° . Calculate the torque your force produces on the wrench, about an axis perpendicular to it and through the bolt.</p><p><img src="https://static.studychannel-prd.pearsonprd.tech/courses/physics/thumbnails/images/f0de3c8b"alt=""/></p>

A metal bar is in the xy-plane with one end of the bar at the origin. A force F = 97.00 N)i + (-3.00 N)j is applied to the bar at the point x = 3.00 m, y = 4.00 m. (a) In terms of unit vectors i and j, what is the position vector r for the point where the force is applied?
