Question

Questions:
1) 2 advantages of wheel and axle
2) 2 advantages of pulley
3) 2 advantages of wedge
4) 2 advantages of inclined plane
5) 2 advantages of screw​

Answer 1

1) When a machine can output a large amount of force compared to the effort that's put into it, it can allow humans to produce more, go faster, lift heavier objects, etc. When speaking about the wheel and axle, specifically, mechanical advantage is helpful in that it allows wheels to rotate faster or move heavier loads.

2)The main benefit of the pulley is that it can actually reduce the amount of force necessary to lift heavy objects and redistributes the direction of the force necessary to lift heavy objects.

3)wedge is that it can take something apart that is really big and it is easier to move.

4)to decrease the amount of force needed to move an object to a certain height.

5) Screw have 25 to 30 percent higher energy efficiency than piston compressors.
