20 mar 2023 · Torque Practice Problems. Problem (1): In each of the following diagrams, calculate the torque (magnitude and direction) about point O O due to the force \vec {F} F of magnitude 10\,\rm N 10N applied to a 4-\rm m 4− m rod. Both the force \vec {F} F and the rode lie in the plane of the page.
Torque Exercises - Solutions. We have three methods for calculating torque about a particular point. R θ Force acts here. F Force acts here. R Force acts here. Use this method if both R and θ are easy to find. Use this method if the lever arm is easy to find. Use if Rr and Fr are easy to break into components.
Write out an equation for the torque acting on the pulley/disk. Write out a third equation relating angular acceleration, and the acceleration of the hanging mass.
Describe how the magnitude of a torque depends on the magnitude of the lever arm and the angle the force vector makes with the lever arm; Determine the sign (positive or negative) of a torque using the right-hand rule; Calculate individual torques about a common axis and sum them to find the net torque
The equation says that the rotational inertia around a parallel axis equals the rotational inertia at the center of mass plus the total mass of the object multiplied by the distance between the two axes squared.
There's only one torque in this problem and it's going to be the torque from the friction force. So that's going to equal . So remember this is just going to be friction times the distance times the sine of the angle equals, and this moment of inertia here.
