If the mechanical advantage of a simple machine is increased, the distance the input force must be applied decreases in relation to the output force. This means that you can exert less input force over a longer distance to achieve a greater output force over a shorter distance.
The actual mechanical advantage is the measured force output divided by the measured force input, while the theoretical mechanical advantage is calculated based on the quotient of the load distance and effort distance. Comparing the two allows us to evaluate the efficiency and effectiveness of the machine in translating input force into output force. Discrepancies between the actual and theoretical mechanical advantages signify losses due to factors like friction, inertia, or other inefficiencies in the system.
The input distance of a single fixed pulley is equal to the output distance. The pulley system doesn't provide a mechanical advantage in terms of distance but does change the direction of the force applied.
The ideal mechanical advantage is based on the geometric relationships of a machine's components and assumes no energy losses, while the actual mechanical advantage accounts for friction, inefficiencies, and other factors that can reduce the output compared to the input force. In reality, the actual mechanical advantage is always less than the ideal mechanical advantage due to these energy losses.
To measure the mechanical advantage of a bicycle, you would compare the input force applied by the rider to the output force produced at the wheels. The mechanical advantage is calculated by dividing the output force by the input force. In the case of a bicycle, the mechanical advantage helps determine how efficiently the rider's pedaling translates into forward motion.
Mechanical advantage of an inclined plane: Ratio of force overcome by nature of weight of mass ( mass * acceleration due to gravity) to force required to move it. Example: ( take g as 10 (m/s)/s ) A mass of 10 kg is on a 30 degree incline , which generates (10 * 10) 100 newtons vertically down, the vector of this parallel to and down the slope is 100 * sin 30 degrees = 100 * 0.5 = 50 newtons which is the force required by the input force, so the ratio = 100:50 = 2:1 which is the mechanical advantage. This is also the ratio of vertical distance travelled by load : distance travelled up the slope
The actual mechanical advantage is usually less, due to losses.

I haven't gotten around to repeating it yet. I've been so busy, had so much homework, the dog ate it, etc.
If a machine was 100 percent efficient, the AMA would be equal to the IMA. This is because in an ideal scenario where the machine loses no energy to friction or other factors, the AMA (actual mechanical advantage) would be the same as the IMA (ideal mechanical advantage).
A simple machine known as a mechanical advantage can compare the output work to the input work. By dividing the output work by the input work, the mechanical advantage provides a ratio that indicates how much the machine amplifies force or motion.
Theoretical mechanical advantage is the ratio of the input force to the output force without considering friction, while actual mechanical advantage includes frictional losses in the machine. If a machine is 100 percent efficient, there will be no frictional losses, so the theoretical and actual mechanical advantages will be the same, resulting in a 1:1 ratio of input force to output force.
Mechanical advantage measures the ratio of output force to input force, showing how much a machine amplifies force. Efficiency, on the other hand, measures how well a machine uses energy and is the ratio of output work to input work. A high mechanical advantage means a machine can achieve a large force output, while high efficiency means a machine minimizes wasted energy during its operation.
