Cylinder rolling down the hill

[QUOTE="jbriggs444, post: 6114211, member: 422467"] The coefficient of static friction tells you how hard you can push something before it "breaks loose" and starts slipping. Say, for instance, you have a 50 kg box on a floor with a coefficient of static friction of 0.1 and gravity of 10 meters/sec^2. You rapidly calculate that you need a horizontal force of 50 * 0.1 * 10 = 50 N to overcome static friction and get it moving. What is the force of static friction if you push the box horizontally with only 40 N? [/QUOTE]
