# Max Angle of Slope

Not what you're looking for?

A flatbed truck is carrying a 20.0-kg crate up a sloping road. The coefficient of static friction between the crate and the bed is 0.400. What is the maximum angle of slope that the truck can climb at constant speed if the crate is to stay in place?
0.381
21.8
23.6
66.4

##### Solution Summary

The maximum angle of slope is determines using Newton's laws with a static friction between the crate and the bed of 0.400.

##### Solution Preview

If Theta is the maximim angle so that the crate stays in place,

Let Mu be the coefficient of static friction
Let N be the Normal force (Gravitational component ...
