The method to calculate mechanical advantage is easy to remember and is necessary when rigging the assembly to accomplish the job. The mechanical advantage of a rigging that will require upward pull can be determined by counting the number of rope lengths running between engaged pulleys and those doing the work. Likewise, if the assembly will require downward pull, count the ropes and subtract one to get the mechanical advantage number. The subtraction is necessary because with the fixed pulley, the downward pull equals the load on the other length of rope so the last "pull" rope does not provide any mechanical advantage.

How do you calculate the mechanical advantage of a moveable pukkey?

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.

How does the different type of pulley system affect the mechanical advantage?

Depending on the type of pulley system you have (Fixed/ movable/ combined pulley) using either of these will give you mechanical advantage. The different pulley types are designed to even the weight of the object your pulled out, this will enable you to lift heavier objects with a lighter pull

What arrangment of movable and fixed pulleys would give a mechanical advantage of 3?

To achieve a mechanical advantage of 3 using pulleys, you can use a combination of fixed and movable pulleys. One common arrangement is to have one fixed pulley and one movable pulley. In this setup, the load is attached to the movable pulley, which is supported by a fixed pulley above it. The user would pull down on the rope, effectively distributing the weight of the load over three segments of rope, resulting in a mechanical advantage of 3.


How is a fixed pulley different from a movable pulley?

A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.A fixed pulley confers no mechanical advantage, but will convert motion in one direction into another direction.A movable pulley system, if the pulleys change their distance from each other, will confer a mechanical advantage.


How are a fixed pulley and a movablepulleydiffrent?

Using a movable pulley is known as using it to 'advantage'. The line going to the movable pulley contributes towards the force acting on the load. A line going to a fixed pulley, only serves to change the direction of the force.
