Can a machine be useful even if its mechanical advantage is less than one?
A machine can be useful even if the mechanical advantage is less than one. It still changes the work a little bit. An example is forks, spoons, lowest gear on bike.
Can you think of a machine that has a mechanical advantage less than 1?
Mechanical advantage is defined as the resistance force moved divided by the effort force used. Sometimes the mechanical advantage of a machine is less than one. That is, a person has to put in more force than the machine can move. Class three levers are examples of such machines.
What happens if the mechanical advantage is less than 1?
A machine with a mechanical advantage of less than 1 does not multiply the force but increases the distance and speed.
Why would you want to use a machine with a mechanical advantage less than 1?
If the mechanical advantage is less than 1, then we will have to apply more force to get the same amount of force output. One can think of this situation as analogous to spending more money but getting a product worth less. In other words, force applied is more than force produced. Hope this helps.
Can a machine be 100 percent efficient Why or why not?
A machine cannot be 100 percent efficient because output of a machine is always less than input. A certain amount of work done on a machine is lost to overcome friction and to lift some moving parts of the machine.
Why the efficiency of a machine is always less than 100?
The percentage of the work input that becomes work output is the efficiency of a machine. Because there is always some friction, the efficiency of any machine is always less than 100 percent.
How does each machine affect the work put into it?
Machines can make work easier by increasing the force that can be applied to an object. A screwdriver increases the force you apply to a screw. A second way that machines can make work easier is by increasing the distance over which a force can be applied. Calculating Power: it is the rate at which work is done.
Can the mechanical advantage of a simple machine be greater than 1?
If the output force is greater than the input force of a simple machine the mechanical advantage is greater than one. If the output force is less than the input force, the mechanical advantage is less than one. Can the actual mechanical advantage of a machine ever be greater then its ideal mechanical advantage?
Can a machine be useful if its velocity ratio is greater?
The velocity ratio is always greater than mechanical advantage in a simple machine. The output work is always less than the input work. Can a machine be useful even if its machinal advantage is less then 1? Machinal advantage, also known as mechanical advantage, refers to the ratio of the force produced by a machine to the force applied to it.
What is meant by Machinal advantage?
Machinal advantage, also known as mechanical advantage, refers to the ratio of the force produced by a machine to the force applied to it. A machine can be useful even its machinal advantage is less than 1. Why is actual mechanical advantage less than ideal mechanical advantage?
What is the mechanical advantage of a 40kg machine?
If you have a input of 40kg and a output of 10kg then the MA is 10/40 or 0.25. If the output force is greater than the input force of a simple machine the mechanical advantage is greater than one. If the output force is less than the input force, the mechanical advantage is less than one.
