3. A car runs on wheels. Explain the load and effort on the wheel and axle used in the tyres of a car.
Answers
Answer:
The wheel rotates around an axle, or fulcrum, so it can keep moving. You can add grease to an axle to decrease the friction between the axle and wheel. ... Wheels reduce or eliminate that friction, like when you place heavy log in a wheelbarrow. Since the friction is reduced, it takes less energy to move the load.
Explanation:
Answer:
Load is the weight which is to be pulled and effort is the force required to take away the load.
Explanation:
Load
Load is the carriage material to be pushed. In case of car it is the body of car and the persons sitting in it. There is limit of this load otherwise car breaks down. So, load must be loaded on car by measuring its limit.
Effort
Effort is the force applied by engine of a car to rotate the axle and push the load. Axle is rotated by the help of engine. As the axle rotates it rotates the wheels. To lessen the effort axle is greased to reduce friction. Force is applied by the tyre on road. In turn frictional force is applied on the tyres to move the body of a car by the ground. It is the friction of ground that make the car move. This type of friction is called as rolling friction.
