Just like bikes, you can lean your motorcycles while riding. You must a question arising in your mind that why don’t motorcycles lean over after leaning so far. You can easily bend and take a turn. The concepts of physics apply here. Two things play a significant role in this case. One of them is fake forces. Another is torque.
You must have studied Newton’s second law of motion in your school books. It states that the product of a body’s mass and acceleration results in its net force. Or we can say that Fnet = ma, where F = force, m = mass and a = acceleration. Here force and acceleration are vector quantities.
If you apply a net force on any object such as a ball, then the ball starts to accelerate. Suppose you keep a ball on a sliding surface and leave it, then it will slowly begin to roll down and fall on the ground. This thing happens because the gravitational force causes an acceleration in it. When the ball is at rest and gravity acts on it, there is no other force acting on it to neutralize the gravitational force. The only way to do this is to add a fake power to the object. The fake effect has to work against the real power on the item. When a motorcycle leans, centrifugal force pushes the driver against the direction of acceleration. To be more specific, centrifugal force works here. Centrifugal force is also known as “center fleeing force.” This force is different from centripetal force.
Torque is the twisting force that causes rotation in any object. There exists a frictional force between the road and tires of a motorcycle. It pushes it to the direction of the center of the circle. All the effects add up to zero if we look at the motorcycle in a reference frame. However, all the sum of all the torques is not zero. Torque can alter an object’s angular velocity. When a bike leans, a gravitational torque exists there for balancing the fake force’s torque. It is strange to know that leaning helps you from falling over.
Motorcycles: Leaning Of A Turning Car
A turning car leans. Several forces act in a single time in case of a for-wheeler, such as torque and reasonable power from the four tires. These forces result in zero net torque. So cars don’t require to lean to turn. But in the case of motorcycles, turning is not possible without making the motorcycles lean.
We often wonder why a motorcycle does not fall when it leans at a turning. Bikes need to bend to turn. Motorbikes do not fall due to two reasons. Torque and fake forces play a significant role here. In the case of a motorcycle, the net torque is not zero. However, in the case of a car, the net torque is not equal to zero. Multiple forces are acting from the four tires of the four-wheeler.
