Does Increasing the angle a ramp makes with the horizontal decreases the mechanical advantage?
True
What is the difference between a force multiplier and a speed multiplier?
A force multiplier increases the effort force and the mechanical advantage is larger than one (Which means it is easier to move a large load with a small effort). While the speed multiplier does not make the effort easier but makes the load move through a larger distance than the effort. The mechanical advantage of a speed multiplier is usually lower than 1.
What is the difference between mechanical advantage and Efficiency?
A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force. This is compensated for by the fact that the distance moved by the input is greater than the output so that in an ideal machine, the work input (Force*Distance) is the same as the work output. In real life, though, you always lose some energy - in the form of frictional heat, or sound.A negative mechanical advantage is the opposite. A small distance moved by the input is converted to a large distance moved by the output. But the force in the output is correspondingly reduced.A mechanism with a positive mechanical advantage is one in which the input force is greater than the output force.

Which is not a way that a machine makes work easier?
Increasing the distance between the load and pivot increases the work output of a machine.
What makes a garlic press a simple machine?
A garlic press uses a lever and has its fulcrum at one end of the lever arm. The load (garlic) is between the fulcrum and the effort. When using a simple machine like the garlic press we gain a mechanical advantage by increasing the amount of force we wish to use.
Why is the actual mechanical advantage of an inclined plane alwaysess than the theoretical mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call an estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less.

True
What is meant by the term mechanical advantage?
A lever is a very useful tool that lets us exchange weight for distance. For example (theoretically) if you had to move a 200 pound sack into a car, but couldn't lift it, you could divide it into 8 parts, each being 25 pounds, and move each one individually into the car. It would be easy, however it would take more distance (lifting into the car 8 times instead of 1)
What is the great advantage of a database?
It makes you store large amounts of data.
How does mechanical breakdown affect chemical breakdown?
Mechanical breakdown makes food smaller so it wasn't be so large for the chemical breakdown.

If the input force on a wheel and axle is 2 Ns and the output force is 20 Ns what is its mechanical advantage?
The mechanical advantage is 10.We use machines to make our work easier and faster.Mechanical advantage gives an idea of how much a mechanism makes our work easier.It is the factor by which the mechanism multiplies the force or torque applied.One way of calculating mechanical advantage is:Mechanical Advantage= (output force)/ (input force)So using this formula to answer the question above, the result is20/2 = 10
What would happen to a pulley system if the load were increased?
Ideal mechanical advantage is the mechanical advantage when there is no friction. It is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load. But actual mechanical advantage will be less than this ideal mechanical advantage due to friction. In other words the efficiency will be less than 100 %. If the efficiency is 80%, it implies 20% is wasted due to friction while lifting a load. If we increase the load the friction also increases and hence the efficiency will decrease with the load.
What if a pulley has a mechanical advantage of 1?
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.

How does the size of a ideal mechanical advantage compares to the mechanical advantage?
This is because the actual mechanical advantage is the actual calculation found after dividing the effort force by the output force. Ideal mechanical advantage is what many people would call and estimate. When estimating mechanical advantage, the numbers are always rounded. This makes actual mechanical advantage less. Sources: Science teacher ------------------------------------------------------------------------------------------------------------------ The answer above is incorrect. The ideal mechanical advantage (IMA) is usually less than the mechanical advantage (MA) in a given machine because of the friction acting on the machine. There will always be some frictional resistance that increases the effort necessary to do the work.
How do you calculate the ideal mechanical advantage of a lever?
It's 1. IMA = Distance in / Distance out. A single pulley doesn't do anything toward mechanical advantage, it changes the direction of the force. Not always. A single-axeled pulley (the typical pulley) has an IMA of 1, having one axel. If there was a second axel, then the IMA would = 2, so on and so forth. The easy way to do it is IMA = # of axels.
