1. The problem statement, all variables and given/known data A man drags a 71.5-kg crate across the floor at a constant velocity by pulling on a strap attached to the bottom of the crate. The crate is tilted 22.5° above the horizontal, and the strap is inclined 64.0° above the horizontal. The center of gravity of the crate coincides with its geometrical center, as indicated in the drawing. Find the magnitude of the tension in the strap. (Image attached) 2. Relevant equations torque = F * l 3. The attempt at a solution Since the crate is not rotating, the torques must balance. From what I can see, there are 3 total torques - two clockwise and one counterclockwise. I set up my equations like this: t1-t3 are the 3 torques. T is the tension on the rope. theta1 is the angle between the box and horizontal. theta2 is the angle between the rope and horizontal. Clockwise Torques t1 = mg * .9/2 * cos(theta1) <--- Torque due to gravity t2 = T * cos(theta2) * .9 * sin(theta1) <- Torque due to horiz. comp. of tension Counterclockwise Torque t3 = T * sin(theta2) * .9 * cos(theta1) <- Torque due to vert. comp of tension Then, t1 + t2 = t3 ; Solved for T. I have a feeling I'm setting up the torque due to gravity wrong. Any thoughts?
