Two friends are carrying a 200kg crate up a flight of stairs. The crate is 1.25m long and 0.500m high and its center of gravity is at its center. The stairs make a 45 degree angle with respect to the floor. The crate is also at a 45 degree angle so the bottom side of crate is parallel to the slope of stairs. If the force of each person is vertical, what is the magnitude of each force? ∑Fy = F1 + F2 - m*g = 0 The attached picture is my attempt at the solution however the two forces I get are wrong. The bottom force according to my physics textbook is 590N and the top force is 1370N. If someone could tell me where in my solution I mess up it would be much appreciated!
