A pulley can either change the direction or the force, but not both. Since a single fixed pulley makes an object go up when pulled down, it has changed direction. So it can't also change force.
Single fixed pulley
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.
The flagpole, because it has the united states of American flag and has 50 stars are on it GO USA.
Mechanical advantage is maximum when weight lifted is extremly high and for which C/W is extremely small so as to be negleted, Max. Mechanical Advantage=1/m
a directional advantage
The mechanical advantage of a pulley can be greater than 1.The efficiency cannot but that is a different matter.
A fixed pulley does NOT multiply the effort force or have a mechanical advantage. It only changes the direction of the effort force. A free pulley multiplies the effort by two. this means the free pulley has a mechanical advantage of 2.information from:www.mhscience02.com
A fixed pulley has a mechanical advantage of 1, which means it doesn't provide any mechanical advantage in terms of force. It changes the direction of the force applied without multiplying it.
A single fixed pulley (:
A pulley system has a mechanical advantage of 1 when the input force equals the output force, resulting in no mechanical advantage. This occurs when the pulley is stationary and only redirects the force, without increasing or decreasing it.
The mechanical advantage of a pulley system is the ratio of the output force to the input force. It is calculated by dividing the load force by the effort force required to lift the load. The mechanical advantage of a pulley system can be greater than 1, making it easier to lift heavy objects.
Its 1 you need more than 1 to improve mechanical advantage i think it's 2 A single pulley means one axel, making the IMA = 1. A double pulley's IMA would = 2, and so on and so forth.
The mechanical advantage of the pulley system in this case is 1:1. This means that the input force and output force are equal, resulting in no mechanical advantage gained.
The ideal mechanical advantage of a fixed pulley is 1, as it does not provide any mechanical advantage in terms of force. The direction of the input (effort) and output (load) for a fixed pulley is the same, as the pulley simply changes the direction of the force applied.
The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
A fixed pulley redirects the force applied to it without providing any mechanical advantage, as it only changes the direction of the force, not the magnitude. Therefore, the mechanical advantage of a simple fixed pulley is always 1.
The simple pulley is the type of pulley that does not have a mechanical advantage.
