Quiz 2 Hint for 1a

Think about the physics here. The direction of the force, W due to the load is straight down. (Click here to see a picture of this much of the problem.)

The force perpendicular to the ramp, Fperp, presses down on the ramp, while the force along the ramp, Fr is the component of the force that moves the object along the ramp.

Here are two points to think about:


What is the angle between Fperp and Fr?


Is
