When their is a caution, and all cars are slower, they all swerve around, to warm up their tires. Why?
some examples of wheel and axle are tyres of cars or trucks,screwdriver,a pencil and pencil sharpener and door knobs are some examples of wheel and axle
For the best answers, search on this site shorturl.im/vS4Qq Check out the definition of mechanical advantage at the referenced site to find your answer. Mechanical advantage is the factor of how much stronger the output force or torque is relative to the input force or torque. If the load actually moves under the applied force or torque, then it moves at a reduced rate equal to the input motion divided by the mechanical factor. The input provides all of the power to the output. Your example, I assume, is a load being lifted or pulled by a rope or cable that wraps around an axle that has an attached handwheel three times the diameter of the axle.
too keep the grip between the tyres and the floor so when they speed up they don't flip over on corners.
Because since there going slow there tires are loosing the heat and the temperature drops down, so they swerve around to keep there tires heated. Warm tires grip better and race cars need to have enough heat in the tires to allow the car to turn properly with out spinning out or skidding.
