Are gears an example of rolling friction?
Gears are not perfect example for rolling friction. Most energy lost in gear operation is due to the surface shear stress, which is more like sliding friction. Rolling friction is due to the pressure induced torque applied on the roll axis. Under this circumstance, the equivalent pressure force doesn't point to the roll axis, which creates a torque to resist the rolling motion. A good example for rolling friction can be a running wheel of the car.
How do you calculate BHP?
You need to measure the torque of the engine. This is best done at the rear wheels using a rolling road dynamometer. You will get a readout giving the torque throughout the rev range. To convert torque into bhp do the following calcluation: bhp = (rpm x torque)/5252
Why does a rolling ball stop rolling?
Friction translates lateral motion to rolling motion, but it can slow down a rolling ball because it opposes the motion of the ball's lower surface to do so. This removes momentum from the ball.When a ball combines rotational and translational motion (rolls), friction acts in the opposite direction of the motion. This in turn should produce a torque by the frictional force i.e,[u.m.g*R] where R=radius of sphere , u = co-efficient of friction. The torque produced should increase the angular acceleration and therefore the body should rotate with greater speed, but as we know, the rolling sphere stops after a certain time.REASON: When a sphere rolls, the surface in contact with the sphere is depressed and the surface just in front of it is raised. So when the rolling sphere strikes this raised surface, the normal reaction instead of passing from center of mass passes through a little bit away in the forward direction of the motion. Therefore the torque produced by this is greater than the torque produced by the frictional force, and opposes the motion of the body until it comes to rest.
What force will stop the ball from rolling after comes down a hill?
Conservation of Energy explains why it speeds up. It also explains why it rolls, due to the frictional force creating a torque.

Two dice are rolled Find the probability that the score on the dice is either 12 or at most 4?
The problem can be split into two parts, rolling a 12, or rolling a 4 or less. This can be further broken down to rolling a 2, rolling a 3, rolling a 4, or rolling a 12. P(rolling 4 or less, or 12) = P(rolling 4 or less) + P(rolling 12) = P(rolling a 2) + P(rolling a 3) + P(rolling a 4) + P(rolling a 12) = 1/36 + 2/36 + 3/36 + 1/36 = 7/36
Which is better perpendicular or parallel bat rolling?
Which is better, perpendicular or parallel bat rolling, will depend on the type of bat you are rolling. If you are rolling an aluminum bat parallel bat rolling is better.
Why are rolling pins heavy?
Not all rolling pins are. The weight helps flatten what you are rolling.
