What is the scientific definition for mechanical advantage?
If you get more force out of a machine than what was put into it, that is mechanical advantage. Levers and gears use this principal to amplify their output.
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.
Why will decreasing the radius of the axle improve the mechanical advantage of a wheel and axle?
it's a mechanical advantage of 1 (meaning no mechanical advantage). This is because no matter how much easier it is to spin a the wheel rather than the axle, its a longer distance of effort force and vice versa. * * * * * True, but that is not what mechanical advantage is! Mechanical advantage IS the trade off between the force required and the distance travelled. You can find the ideal mechanical advantage of a wheel and axle by dividing the radius of the wheel by the radius of the axle. * * * * * Better. But I think it could be either of the two reciprocal ratios of the radii, depending on whether the wheel/axle is being used in a 2nd class or 3rd class lever configuration ... i.e., are you cranking the wheel in order to turn the axle, as in a winch, or spinning the axle in order to turn the wheel, as in a motor-vehicle ?
How machines make work easier?
Simple machines using pulleys and levers, make the work easier by using mechanical advantage. The input force is less than the output, but spead over a larger distance and time. Other machines harness engines and motors, to take over the human input. The motors and engines need a separate source of energy.
Does a machine make work easier by multiplying force you exert?
yes
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)

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 are the pros and cons of a mechanical system?
Disadvantage: They are powered on batteries Advantage: They mke life easier
What is the mechanical advantage of something with an effort force of 10 N and an resistance of 5 N?
The mechanical advantage of such a thing is that it will make work easier. This is because it requires very little force to operate.
Which would increase mechanical advantage?
A mechanical advantage greater than one means you can perform more work than the effort you expend. The mechanical advantage gives you more capability. A mechanical advantage of only 1 means you really do not have any advantage.
What is making it easier to lift the load?
The mechanical advantage of the block and pulley you are using, or the engine of the fork lift truck if that is what you are using.
Advantage of dynamic braking in dc machines?
This helps the machine to stop easier. It is a much easier process to use and safer for everyone involved in the process.
Is a bike a machine?
a machine is anything that is used to make life easier. if you could bike a mile or walk a mile the bike would be easier and faster. so yes it is a machine
What factor affect the mechanical advantage of a simple machine?
The more moving/mechanical components in a system the greater likelihood of a part failing. remember that no part is ever manufactured exactly, there is always a tolerance (an amount the dimension/specification can vary by) cumulatively this increase the more parts you add. Basically a simple machine has less things that can break and is easier to maintain.
What new inventions made farming easier for settler?
an iron plow, lightweight steel plow, mechanical reapers, mechanical drill, threshing machine, and a horse-drawn hay rake
