Awooden shipping crate that weighs 816 1 b is placed on a loading ramp that makes an angle of 25
with the horizontal. to keep the crate from sliding, a chain is hooked to the crate and to a pole at the
top of the ramp. find the magnitude of the components of the crate's weight (disregarding friction)
perpendicular and parallel to the incline.
a) perpendicular: 816 lb parallel: 25 lb
b) perpendicular: 740 lb parallel: 345 lb
c) perpendicular: 25 lb
parallel: 816 lb
d) perpendicular: 345 lb
parallel: 740 lb
