high, and its center of gravity is at its center. The stairs make a 45.0° angle with respect to the floor.
The crate also is carried at a 45.0° angle, so that its bottom side is parallel to the slope of the stairs
(Fig. 11.51). If the force each person applies is vertical, what is the magnitude of each of these
