Question

12. Which machine do you think will be better if you have to load heavy boxes in a lorry-a
pulley or an inclined plane? Justify your answer.​

Answer 1

Answer:

Therefore, an inclined plane acts as a force multiplier. Thus, it can be used to lift heavy loads. Example : If a heavy box needs to be loaded on a lorry, it is far easier to push it over an inclined plane than to lift it up. Steeper the inclined plane, greater will be the effort required to push up the load.
