Respuesta :
The mechanical advantage of a wheel and axle is the radius of the wheel divided by the radius of the axle. Wheel and axle B has the greater mechanical advantage.
As we know The mechanical advantage of a wheel and axle is the radius of the wheel divided by the radius of the axle.
[tex]\rm \bold{ M.A. = \frac{R}{r} }[/tex]
Where,
R - radius of the wheel
r - radius of the axle
So we can say that the the mechanical advantage is the high when R is much bigger than the r.
In case A, the R is very close to the r. So in this case the mechanical advantage will be less.
In case B, the R is much bigger than the r. So, in this case mechanical advantage will be greater.
Hence, we can conclude that wheel and axle B has the greater mechanical advantage.
