A crate is held at rest on a smooth ramp by a rope. The rope is parallel to the ramp.
The ramp makes an angle of 25∘25^{\circ}25∘ with the horizontal.
The weight of the crate is 400 N.
Assume there is no friction between the crate and the ramp.
Explain how a scale vector diagram can be used to determine the tension in the rope and the normal contact force of the ramp on the crate.
Your answer should include estimates of the size of each force.
