Speed. It's nice to be able to drive the wheel faster than the rpm's your legs can produce on the front gears.

Does MA stand for Mechanical Advantage?

It could, or Master of Arts.


What is the difference between actual machanical advantage and ideal machanical advantage?

Ideal mechanical advantage is what could be obtained without the effects of gravity and friction lowering the efficiency of the machine. The actual mechanical advantage is what can actually be obtained by the machine.


What is meant by the term mechanical advantage?

A lever is a very useful tool that lets us exchange weight for distance. For example (theoretically) if you had to move a 200 pound sack into a car, but couldn't lift it, you could divide it into 8 parts, each being 25 pounds, and move each one individually into the car. It would be easy, however it would take more distance (lifting into the car 8 times instead of 1)


What is theoritical mechanical advantage?

The theoretical mechanical advantage is the ratio of the input force to the output force in a simple machine without accounting for energy losses due to friction or other factors. It represents the ideal mechanical advantage that a machine could achieve under perfect conditions.


What is the equation for mechanical advantage?

Mechanical Advantage: F(out)/ F(in) Actual Mechanical Advantage is the ratio of Force outputed to Force inputed. (AMA=Fo/Fi) Similarly, IMA (Ideal Mechanical Advantage) = di/do


What would increase the mechanical advantage of a second class lever?

Increasing the distance between the pivot point and the effort force, or decreasing the distance between the pivot point and the load, could increase the mechanical advantage of a second-class lever. Additionally, using a longer lever arm can also increase the mechanical advantage.


How can you increase mechanical advantage of a gear system?

A mechanical advantage occurs when a tool such as a hammer is used that increases the amount of force being applied without increasing the effort of the person using the tool. To increase mechanical advantage, you could use a bigger hammer to increase output force.


Why will decreasing the radius of the axle improve the mechanical advantage of a wheel and axle?

it's a mechanical advantage of 1 (meaning no mechanical advantage). This is because no matter how much easier it is to spin a the wheel rather than the axle, its a longer distance of effort force and vice versa. * * * * * True, but that is not what mechanical advantage is! Mechanical advantage IS the trade off between the force required and the distance travelled. You can find the ideal mechanical advantage of a wheel and axle by dividing the radius of the wheel by the radius of the axle. * * * * * Better. But I think it could be either of the two reciprocal ratios of the radii, depending on whether the wheel/axle is being used in a 2nd class or 3rd class lever configuration ... i.e., are you cranking the wheel in order to turn the axle, as in a winch, or spinning the axle in order to turn the wheel, as in a motor-vehicle ?


Is it true a simple machine is one that always gives a mechanical advantage of 2?

Oh, what a lovely question! A simple machine is a device that helps make work easier by either changing the direction or amount of force needed. While some simple machines, like a lever or pulley, can provide a mechanical advantage of 2 or more, not all simple machines will have a fixed mechanical advantage. Each simple machine is unique and can provide different levels of mechanical advantage depending on its design and how it is used. Just like how every brushstroke on a canvas adds to the beauty of a painting, each simple machine plays its own special role in making tasks easier and more efficient.


What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?

Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.


What is Fishing road mechanical advantage or disadvantage?

A fishing rod provides a mechanical advantage by allowing the angler to cast their baited hook further into the water than they could by hand. However, a disadvantage is that fishing rods can be bulky and cumbersome to transport, especially for anglers who need to hike to remote fishing spots.


What is the mechanical advantage of using machines?

Mechanical advantage is the ratio of output force to input force. In other words, F out/F in. Output force is the work done by the machine while input force is what the host (you) did to the machine. Work is always displayed with the label of joules.
