To find: The magnitude of the force required to keep the van from rolling down the hill and the force perpendicular to the hill.
Answer to Problem 62RE
The magnitude of the force required to keep the van from rolling down the hill and the force perpendicular to the hill are
Explanation of Solution
Given information:
The force is
The angles are
Calculation:
Draw the diagram to show the position of the ramp, van and force applied on it.
The above figure shows that the triangle ABC and BDE are similar so
Calculate the magnitude of the force
Apply the cosine function in triangle BED.
Therefore, the magnitude of the force required to keep the van from rolling down the hill and the force perpendicular to the hill are
