A man drags a 78.0-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 26.5° above the horizontal, and the strap is inclined 56.5° above the horizontal. The center of gravity of the crate coincides with its geometrical center. Find the magnitude of the tension in the strap. Crate is .9m long by 04m high.
