The ideal (not idea) mechanical advantage is 30/4 = 7.5
diameter is longer. radius is half of diameter
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.

the mechanical advantage is noting
Since mechanical advantage would be helpful for this situation, the diameter of the steering wheel is larger than the typical steering wheel. Increasing the diameter of the steering wheel allows for a large mechanical advantage.
The spokes of a wheel are comparable to levers. Longer spokes give more mechanical advantage. Even in a wheel that is solid, and has no spokes, the greater the diameter, the greater the mechanical advantage.
It is 30/4 = 7.5

it really depends on the machine you are talking about. there are 6 simple machines: the lever, wheel and axle, pulley, inclined plane, wedge, and the screw. Lever = (distance from fulcrum to effort) divided by (distance from fulcrum to resistance) Wheel and Axle = (diameter of the wheel) divided by (diameter of the axle) Pulleys = the # of pulleys used Inclined Plane and Wedge = (length of slope) divided by (height) Screw = (circumference) divided by (pitch) Hope this helped :)

Holding the diameter of the screw constant, closely spaced threads (fine pitch) have a higher mechanical advantage than thread which are spaced farther apart (course pitch). Mechanical advantage is the ratio of travel of the applied force to the ratio of the imparted force. Because the screw must rotate more times to insert a given depth, fine pitch has a higher mechanical advantage.
The velocity factor of a wheel depends on its diameter. If we take the velocity factor as a measure of how far the vehicle moves in one revolution of the wheel, then it is equal to the circumference of the wheel, which is pi times the diameter.
