Rolling Friction Practice Problems
1. Considering a static friction, a 1000 kg crate push across a horizontal floor is at a constant speed. A coefficient of rolling friction per one the crate and floor unit is 0.06. What is the force needed for pushing the truck?
2. The bike covers twenty meters on the down-slope at a continuous pace of twenty meters per second. The coefficient of rolling resistance of the bicycle tires and the road have 0.09 as the value. What is the magnitude of rolling friction (restructure material) that acts on the bicycle?
3. A box with 2900 kg weight is moving straight out on the floor with the ground speed. The rolling resistance between the crate and the floor is equal to 0.09. what is the acceleration?
4. Derive the rolling friction force for a rolling object with radius of curvature = 60 meters and at 5000 kg load by making use of the relevant formula.
5. Derive the rolling friction force for a rolling object with radius of curvature = 0.8 meters and at 5 kg load by making use of the relevant formula.
Rolling Friction
Rolling Friction is a frictional force that opposes rolling objects. Rolling friction is applicable where the body moves along its curved surfaces. For example, wheels in vehicles, ball bearings, etc. are examples of rolling friction.
In this article, we will learn about rolling friction, its definition, laws, formulas, causes, coefficient, and the factors that affect it. We will also learn how rolling friction is different from sliding friction.
