Introduction of the frictional force of mountain bike equipment


1, why is the mountain bike steel ball? In the mountain bike's front axle, axle, rear axle, handlebar rotation, pedal rotation and other places, are a steel ball. People riding a mountain bike always want to be relaxed, flexible and effortless. And rolling instead of sliding can greatly reduce the friction, so in the mountain bike to place the installation of steel ball, we can often add lubricating oil, so that the contact surface to leave each other, so that the friction can become smaller.
2, mountain bike tires Why should there be uneven pattern? The size of the friction is related to two factors: the size of the pressure, the roughness of the contact surface. The greater the pressure, the greater the friction; contact surface more rough, the greater the friction. The mountain tires have a flattery pattern, which is to increase the friction between the mountain bike and the ground, in order to prevent the mountain bike from slipping.
3, after the brake, why can the mountain bike stop? Brake, the friction between the brake pads and the wheel, will hinder the rotation of the rear wheel. The greater the pressure of the hand, the greater the pressure on the rim of the brake pads, the greater the friction is generated, the slower the rear wheel turns. If completely stopped, then the friction between the rear wheel and the ground becomes sliding friction (the original rolling friction, the direction forward), the direction of backward, hinder the mountain bike movement, so stopped.
