Why is it important that the diameter of the wheel be greater than the diameter of the axle in a wheel and axle?

because the wheel turns through a much greater distance than the axle.
but the smaller turn of the axle is more powerful.witten by-brenda v.
=========================
Answer #2:
-- The fact that the wheel turns through a greater distance that the axle does
is a result, not a cause, of the wheel being bigger than the axle.
-- The axle is not more powerful than the wheel. Ignoring losses, they must both
have the same power. The axle's force is greater than the wheel's force, but to pay
for it, the axle must turn through greater distance. Same as all the lever stuff.
-- The diameter of the wheel needs to be greater than the diameter of the axle
only if you'd prefer not to have the axle scrape on the ground.

What is the mechanicatage advantage of a wheel and axle when the wheel has a diameter of 15 inchesand the axle has a diameter of 3 inches?
the mechanical advantage is noting
Is a crank a wheel and axle?
Yes It is. The wheel is where you hold and the axle is the part where it is conected to the object.
What type of simple machine is a car jack?
Wheel and axle could be the type of simple machines because it has a wheel for it could advance to the front and to the back, and what the axle do is that is making the wheel move and its at the bottom of the toy car or any car
What is another name for wheel and axle?
driveshaft
How does a wheel and axle change its force?
A wheel requires a smaller amount of force to be moved than an axle. Combined, a minimal amount of force is used to move the wheel and in turn is transferred from the wheel to the attached axle, to move the axle. Alone the axle would require a greater amount of force for it to be turned.
In a wheel and axle simple machine why is it important that the diameter of the wheel be greater than the diameter of the axle?
what kind of stupid question is this? if the dia of the axle is larger then that of the wheels, the axle becomes the wheel and the "wheels" become the axle
Is it true that the diameter of an axle is always greater than the diameter of a wheel?
No, quite the opposite.
What is the mechanicatage advantage of a wheel and axle when the wheel has a diameter of 15 inchesand the axle has a diameter of 3 inches?

What is the scientific definition of a wheel and axle?
an axle to which a wheel is fastened so that torque applied to the wheel winds a rope or chain onto the axle, yielding a mechanical advantage equal to the ratio of the diameter of the wheel to that of the axle.
Why are a wheel and axle important?
A wheel and axle is important because, you can make lifting boxes lighter
How are a lever and a wheel and axle similar?
To find the Mechanical Advantage you would have to divide.The equation for Lever is: MA = Length of effort arm--------------------------------Length of resistance armThe equation for Wheel and axle is: MA = Diameter of wheel-------------------------Diameter of axleORMA = Diameter of axle-----------------------Diameter of wheel* Depending on where the force is applied.A wheel is just like a bunch of levers arranged in a circle with the fulcrum at the center of the wheel. The axle is like the short end of the lever.One degree of rotation of the axle results in one degree of rotation of the wheel; this is just like rotating the short end of the lever to movethe long end.
Why are small wheels bad for a mousetrap car?
Larger wheels have a larger diameter. Therefor, they will cover a greater distance per rotation of the driven axle, compared to a smaller wheel.
On a wheel and axle where would you apply force to make a greater force?
Probably on the axle??
What is the formula of velocity ratio of a wheel and differential axle?
velocity ratio= 2D/(d1 - d2) , where D = diameter of effort wheel,d1&d2= diameter of the axles.
What is the idea mechanical advantage of a wheel with a diameter of a 30 cm fixed to an axle with a diameter of 4 cm if the axle is turned?
The ideal (not idea) mechanical advantage is 30/4 = 7.5
What is the mechanical advantage of a a wheel and axel?
The mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle. Ex:- Suppose the radius of the wheel is four times greater than the radius of the axle, every time you turn the wheel once, your force will be multiplied four times.
When a force is applied to a wheel does its axle exert a greater force?
no or maybe yes
