I'm thinking now that there is no torque due to gravity (no lever arm) and that the fact that the box is in equilibrium with a constant velocity has some importance.
That is, there is one equation for torque from tension: t1 = T*sin(theta2) * .45*cos(theta1)
and the other torque equation to...
Homework Statement
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...
