The mechanical advantage (MA) of a pulley system is calculated using the formula: MA = Load Force / Effort Force. For a simple pulley, the MA is typically 1, as the effort needed to lift the load is equal to the load itself. However, in systems with multiple pulleys (block and tackle), the MA can equal the number of rope segments supporting the load. Thus, the more pulleys used, the greater the mechanical advantage.

IMA of a pulley= the number of ropes supporting the load. An easier way is to count how many times the rope wraps around the wheel. :)
The mechanical advantage (MA) of a lever is calculated using the formula: MA = Length of effort arm / Length of resistance arm. The effort arm is the distance from the fulcrum to where the effort is applied, while the resistance arm is the distance from the fulcrum to the load being moved. This ratio indicates how much the lever amplifies the input force. A higher MA means the lever provides greater force amplification.
The mechanical advantage (MA) of a ramp is calculated as the ratio of the length of the ramp to its height. Given a ramp length of 10 meters and an MA of 5, the height can be calculated using the formula: height = length / MA. Thus, the height of the ramp is 10 meters / 5 = 2 meters.

The formula to calculate the mechanical advantage of a pulley system is MA 2 number of movable pulleys.
The pulley formula used to calculate the mechanical advantage of a system involving pulleys is MA 2n, where MA is the mechanical advantage and n is the number of pulleys in the system.
The formula for the mechanical advantage of a pulley system is MA = 2 * (number of support ropes). This means that for every additional support rope, the mechanical advantage of the pulley system doubles.

The mechanical advantage (MA) of a pulley system is calculated by counting the number of ropes supporting the moving block or load. For a single fixed pulley, the MA is 1 as it changes the direction of the force but does not provide any mechanical advantage. For a system with multiple pulleys, the MA is equal to the number of ropes supporting the load.

The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
To calculate the mechanical advantage of a movable pulley system, you divide the load force by the effort force. The formula is MA = Load Force / Effort Force. The mechanical advantage of a movable pulley is always 2 because the effort force is half the load force when using a system with a movable pulley.
E=l/2 2=l/e or l/e=2 ma =l/e ma of single moveable pulley is : l/e=2
The tension formula for a pulley system is T 2F, where T is the tension in the rope and F is the force applied to the system.
The velocity ratio of a pulley system is the ratio of the rotational speed of the driving pulley to the driven pulley. It indicates how the speed of the driven pulley relates to the speed of the driving pulley. The formula is: Velocity Ratio = Diameter of driving pulley / Diameter of driven pulley.
The formula used to calculate mechanical advantage in a pulley system is: Mechanical Advantage Number of supporting ropes or strands.
