There are many situations where knowing whether an item will slide on an inclined plane is

important either for safety or correct operation.

For example, packages moving around a distribution centre may need to be transported on inclined rubber conveyor belts without sliding, but also be delivered to chutes that they should slide down freely. How can an engineer determine whether an object will slide or remain in place on an inclined plane?
