Respuesta :

Mechanical advantage is given by formula

[tex]MA = \frac{F_{out}}{F_{in}}[/tex]

here we know that for torque balance in pulley system we have

[tex]F_{out}\times r_1 = F_{in}\times r_2[/tex]

[tex]MA = \frac{r_2}{r_1}[/tex]

for W

[tex]MA = \frac{12}{4} = 3[/tex]

for X

[tex]MA = \frac{36}{9} = 4[/tex]

For Y

[tex]MA = \frac{18}{3} = 6[/tex]

For Z

[tex]MA = \frac{16}{8} = 2[/tex]

so least to greatest order will be

Z < W < X < Y

so correct answer is

B- Z, W, X, Y
