When a machine increases the size of the output force what happens to the output distance?
7. Calculate How much work is done when a 50 N force is applied to a 0.30 m screwdriver to lift a paint can lid? When a machine changes the size of the output force, the distance must change. When the output force increases, the distance the object moves must decrease.
When a machine increases the input force what happens to the input distance?
Machines may increase the strength of the force, increase the distance over which the force is applied, or change the direction in which the force is applied. There are six types of simple machines.
How do machines increase the distance of your force?
The output distance may or may not be the same as the input distance. Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied.
Does a machine increase the output force?
Mechanical Advantage of Different Types of Machines Other machines increase the distance over which the force is applied but decrease the strength of the force.
When a simple machine increases the force you exert what other factor changes?
A machine makes work easier by changing at least one of three factors. A machine may: change the amount of force you exert, • change the distance over which you exert a force, or • change the direction in which you exert a force. Input and Output Forces When you do work, you exert a force over some distance.
Can a simple machine change the amount of force?
Simple Machines are tools that make work (using a force to move an object) easier. Simple machines can change the direction of a force or the amount of force needed. A simple machine has few or no moving parts and only one force is applied to it.
Does a pulley increase the distance?
A pulley increases the distance over which a force does work.
What happens to the input distance when the input force decreases?
Tire jack Lug wrench Rowing oar Summary: As input force decreases, the input distance increases.
Can simple machines Trade force for distance?

How do simple machines affect force?
There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied. The wheel and axle is a machine in which the wheel is attached to a central axle.
When a simple machine multiplies force it decreases?
When a simple machine multiplies force, it decreases the distance moved.
Do pulleys reduce the distance?
Pulleys are usually Force Multipliers – using a simple machine such as a pulley can effectively multiply the force your body produces. However, the rope must be pulled much further because the pulley reduces the distance the object moves.
How does a movable pulley increase the output force?
This type of pulley doesn't change the direction of the force applied to it, but it increases the force by a factor of 2. In a compound pulley, two or more rope segments pull up on the load, so the ideal mechanical advantage is 2 or greater than 2.
Does the output force increase or decrease?
the output displacement is reduced in the same proportion by which the output force is increased over the input force.
What is output force?
The output force is the force that you would need to lift the object without the inclined plane. This force is equal to the weight of the object.
How does the travel distance of the load change as you increase the number of pulleys from one to two then three then four?
C) How does the travel distance of the load change as you increase the number of pulleys from one to two, then three, then four? The travel distance of the load becomes half, then one-third, then one-fourth.
Why do pulleys increase distance?
As they rise up, they gain a certain amount of potential energy equal to their weight multiplied by the distance they move. You lose exactly the same amount of energy—equal to your weight (four times smaller) times the distance you move (four times larger).
How do pulleys affect force?
Using multiple pulleys decreases the amount of force necessary to move an object by increasing the amount of rope used to raise the object. The mechanical advantage (MA) of a pulley system is equal to the number of ropes supporting the movable load.
What is an output distance?
What is the definition for output distance? The distance an output force acts through in a machine. What is the definition for work output? The work done by a machine as the output force acts through the output distance.
How will adding more pulleys affect the input force needed to lift the load?
Using multiple pulleys decreases the amount of force necessary to move an object by increasing the amount of rope used to raise the object. The mechanical advantage (MA) of a pulley system is equal to the number of ropes supporting the movable load.

How do pulleys effect force?
Using multiple pulleys decreases the amount of force necessary to move an object by increasing the amount of rope used to raise the object. The mechanical advantage (MA) of a pulley system is equal to the number of ropes supporting the movable load.

What increases the work output of a machine?
The only way to increase the work output is to increase the work input. You can't get more work out of a machine than you put into it. The moving parts of a machine must use some of the work input to overcome friction. Because of friction, the work output of a machine is always less than the work input.

How do you increase pull power with a pulley?

How does a pulley increase force?
Using a pulley greatly multiplies the force of your physical efforts. A pulley with one wheel allows you to reverse the direction of your lifting force by pulling down on a rope (that's looped over the wheel), lifting your weight.
How does the input distance of a machine compare to the output distance?
How does the input distance of the machine compare to its output distance? Because the output force is greater than the input force, the input distance must be greater than the output distance.
What is the distance moved by effort?
The ratio of the distance moved by the effort to the distance moved by load is called as the velocity ratio.
How do you increase the power of a winch?
If you want to double the power of your winch, or if the anchor point is too close to let out enough cable for a strong pull, use a snatch block to double the line. Using a snatch block will double your load capacity and will allow you to spool out more cable to reach the maximum rating of your winch.
