Question

Tangential force method The tangential force method involves finding the component of the applied force that is perpendicular to the displacement from the pivot point to where the force is applied. This perpendicular component of the force is called the tangential force. (Figure 2) Learning Goal To understand the two most common procedures for finding torques when the forces and displacements are all in one plane: the moment arm method and the tangential force method Part A The purpose of this problem is to give you further practice finding torques in two-dimensional situations. In this case it is overkill to use the full cross product definition of the torque because the only nonzero component of the torque is the component What is Ft, the magnitude of the tangential force that acts on the pole due to the tension in the rope? Express your answer in terms of T and ? Figure 2014 Submit When using the tangential force method, you calculate the torque using the equation where d is the distance from the pivot to the point where the force is applied. The sign of the torque can be determined by checking which direction the tangential force would tend to cause the pole to rotate (where counterclockwise rotation implies positive torque).

Explanation / Answer

A: Ft = Tcos(theta)

G. Either method may be used, since the required variables are present in the diagram.

Find Rm. Rm = Lcos(theta)
