One student group has decided to design a device where a toy car (10 grams) must apply a force to lift a 50-gram weight 2 inches in the air. What simple machine could the group use, and what mechanical advantage would they need to achieve their goal?

Respuesta :

here the simple machine must be a pulley system that can be used here

When pulley system is used as simple machine the force applied by 10 g car is able to pull the 50 g weight by 2 inch in air

So here Mechanical advantage can be defined as

[tex]MA = \frac{output}{input}[/tex]

here for output we will have

[tex]output = 50gram* 2 inch[/tex]

similarly for input

[tex]input = 10 gram * 2inch[/tex]

now the mechanical advantage will be given as

[tex]MA = \frac{50 gram * 2 inch}{10 gram * 2inch}[/tex]

so here we have

[tex]MA = 5[/tex]

so we have mechanical advantage of 5
