Not entirely sure what you mean but maybe this will help: In general the more pulleys you have in your system the less force you will need to apply to lift a certain load, in this case the system of pulleys is generally called a "block and tackle".
The effort force is applied at the handle of the shovel. The fulcrum is where your other hand goes, lower down the shaft, and the fulcrum resistance would be where the load goes on the shovel, I.E the flat bit that you hit people with!
The input force or the effort on a pair of scissors would be the force applied by your hands on the handles. The output force or load would be the blades of the pair of scissors.
if your mother gives an effort to settle a compromise it would be to do your freaking homework and open a book
An inclined plane can help make work easier because it makes less effort then simply lifting it up. <(^^)> <(^^<) <(^^)> (>^^)> <(^^)> THAT IS THE WRONG ANSWER THE REAL ANSWER ->

A pulley system with a mechanical advantage of 4 would require the least amount of effort force to lift a load. This means that for every 4 units of load force, only 1 unit of effort force is needed.
In a movable pulley system, the effort force required would be equal to half the weight being lifted. So to lift a 300 kg weight, you would need to apply an effort force of 150 kg (approximately 1471 Newtons) assuming ideal conditions and neglecting friction and other losses.
actually, the effort force would be decreasing, and the effort distance would be increasing!
A system with a single fixed pulley would require the least effort force to lift the load. In this system, the load is attached to the rope that passes over the pulley, with the other end of the rope attached to an anchor point. This arrangement changes the direction of the force required to lift the load, making it easier to lift.
Increasing the length of the effort arm in a lever system would require less force to lift the load, increasing the mechanical advantage. This would result in the load moving a greater distance compared to the effort arm, but it would require a longer distance to move the load. Also, the trade-off would be a lower speed in moving the load.
The mechanical advantage is given by the ratio of resistance force to effort force. It represents the factor by which a simple machine multiplies the force applied to it. Mathematically, it can be calculated as mechanical advantage = resistance force / effort force.
With a fixed pulley, the effort force would be equal to the weight being lifted (300kg) in this case. So, to lift 300kg using a fixed pulley, you would need to apply an effort force of 300 kg-force.
The effort force required would be 10 N. This is because mechanical advantage is calculated as Load force/Effort force, so the Effort force = Load force/Mechanical advantage. In this case, 30 N (Load force) divided by 3 (Mechanical advantage) equals 10 N for the Effort force.
The effort force required to lift a 10kg load would be equal to the weight of the load, which is 10kg multiplied by the gravitational acceleration, which is approximately 9.81 m/s^2. So, the effort force would be approximately 98.1 Newtons.
If the effort force for a lever is 50 Newtons and there is no friction, then the resistance force would also be 50 Newtons in an ideal situation with a first-class lever and IMAAMA. This is because in this case, the input force (effort force) is equal to the output force (resistance force) due to the principle of moments.
With a movable pulley system, you would need to exert an effort force equal to half the weight being lifted. In this case, to lift a 300kg weight, you would need to apply an effort force of 150kg. This is because movable pulleys provide a mechanical advantage of 2, reducing the amount of effort force needed.
Effort force is a force used to move an object over distance.Which ball will bounce higher lacrosse ball or tennis ball?Read more: Which_ball_will_bounce_higher_lacrosse_ball_or_tennis_ball
