The mechanical advantage of a wheel and axle is the radius of the wheel divided by the radius of the axle. On wheel and axle A, the wheel and axle are very close in size. On wheel and axle B, the radius of the wheel is much greater than the radius of the axle.
Answer:
The wheel and axle B has a greater mechanical advantage than wheel and axle B
Explanation:
Given
Let
[tex]R_W = Radius\ of\ the\ wheel[/tex]
[tex]R_A = Radius\ of\ the\ axle[/tex]
[tex]MA = \frac{R_w}{R_A}[/tex]
Required
Which wheel and axle has the greater mechanical advantage? (Missing Information)
For Wheel and Axle A:
[tex]R_w[/tex] is close to [tex]R_A[/tex]
For calculation purpose, we can assume that:
[tex]R_W \approx\ R_A[/tex]
So:
[tex]MA = \frac{R_w}{R_A}[/tex]
[tex]MA = \frac{R_A}{R_A}[/tex] or [tex]MA = \frac{R_W}{R_W}[/tex]
[tex]MA = 1[/tex]
For Wheel and Axle B:
[tex]R_w[/tex] far from [tex]R_A[/tex]
For calculation purpose, we can assume that:
[tex]R_W > R_A[/tex]
and
[tex]R_A = nR_A[/tex]
Where:
[tex]n > 1[/tex]
So:
[tex]MA = \frac{R_w}{R_A}[/tex]
[tex]MA = \frac{nR_A}{R_A}[/tex]
[tex]MA = n\frac{R_A}{R_A}[/tex]
[tex]MA = n * 1[/tex]
[tex]MA = n[/tex]
Since: [tex]n > 1[/tex]
Then
[tex]MA > 1[/tex]
So, we have:
[tex]MA = 1[/tex] ---> For Wheel and Axle A
[tex]MA > 1[/tex] ---> For Wheel and Axle B
By comparison, the wheel and axle B has a greater mechanical advantage than wheel and axle B

You look out the window and wonder "am I good enough"
You cut the lines on your wrist, and cry as the blood streams down your arm
You drink until there is nothing else you can do but go to sleep
You swallow the pills as if they where normal to you
You say why does it happen to me
You starve yourself to try and look like the others
You hang from the tree as if you thought you could fly into the sky
and you did
You did it... thinking your pain is all gone now
But what you don't know
Is now your family has to go through the same pain as you did
Saying "what could I have done to help"
And now they are gone now to
