A mechanical advantage greater than one means you can perform more work than the effort you expend. The mechanical advantage gives you more capability. A mechanical advantage of only 1 means you really do not have any 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.
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 the unit for mechanical advantage

IMA- Ideal mechanical advantageAMA- Actual mechanical advantage
Since the Mechanical Advantage of the inclined plane is inversely proportional to its height, increasing the height would lower your mechanical advantage and lowering the height would increase it.Alternately, mechanical advantage is directlyproportional to an inclined plane's length, therefore increasing the length would increase your mechanical advantage.
Increasing the length of the ramp or decreasing the angle of incline would increase the mechanical advantage of a ramp. This would make it easier to move objects up the ramp by requiring less force.
Simple machines increase mechanical advantage.
Common mechanisms for obtaining mechanical advantage would include such as multiple pulleys, hydraulic systems, gears, and levers.
Increase the advantage.
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.
Increasing the length of a ramp does not change the mechanical advantage, as mechanical advantage depends on the ratio of the output force to the input force. The length of the ramp affects the distance over which the force is applied, but not the mechanical advantage itself.
You can increase the mechanical advantage of a pulley system by adding more pulleys to the setup. As the number of pulleys increases, the mechanical advantage also increases. This allows you to lift heavier loads with less force.
To increase the mechanical advantage of a third-class lever, you can adjust the distances between the effort force, the fulcrum, and the load. By increasing the length of the effort arm or decreasing the length of the load arm, you can increase the mechanical advantage.

Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
