Question

The table shows dimensions of four wheel and axles.

Which shows the order of mechanical advantage from least to greatest?

A- Y, X, W, Z

B- Z, W, X, Y

C- Z, X, W, Y

D- Y, Z, W, X



Answe is b

Answer 1

b

Step-by-step explanation:

Answer 2

Mechanical advantage is given by formula

`MA = (F_(out))/(F_(in))`

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

`F_(out)* r_1 = F_(in)* r_2`

`MA = (r_2)/(r_1)`

for W

`MA = (12)/(4) = 3`

for X

`MA = (36)/(9) = 4`

For Y

`MA = (18)/(3) = 6`

For Z

`MA = (16)/(8) = 2`

so least to greatest order will be

Z < W < X < Y

so correct answer is

B- Z, W, X, Y
