The resistance force multiplied by the resistance distance.
Scissors are a simple machine. A simple machine makes work easier to do. (not hard work) What type of simple machine are they? They are a lever. Levers have fulcrums or pivot points. The pivot point of the scissors are the crossing section.
Simply put, a simple machine makes the work much easier. Simple machines reduce the amount of force needed to do the work. A pulley, for instance, is a great example of a simple machine.
Every real machine is subject to forces that reduce output. These include actual forces such as friction, or human controlled forces such as imperfect machining. This reduces the output to less than the ideal.
simple machines are put together by connecting. for example, in cars. simple machines work together by putting their strength
Efficiency % = (work out / work in) * 100 (Work = force * distance)
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
Increasing the input force or the distance over which the force is applied can increase the work output of a simple machine. Reducing friction within the machine can also help to increase its efficiency and work output.
the work a machine does is the work output what it takes to do the work is the work input
The work ouput of the second machine will usually be more than the work input of the first machine.
When the input work on a simple machine equals the work output, the machine is said to be 100% efficient. This means that all the input work has been converted into useful output work, with no energy lost due to friction or other inefficiencies in the machine.
If a simple machine is 100% efficient, it means that the input work done on the machine is equal to the output work produced by the machine. In other words, all the energy put into the machine is completely converted into useful work without any energy being wasted.
Work input.
If a simple machine provides an increased output force, then the output distance will decrease. This is due to the principle of work conservation, where input work equals output work. As the force increases, the distance through which the force acts decreases proportionally to maintain the balance.
Yes, when the input work on a simple machine equals the work output, the machine is said to be 100% efficient. This means that all the work put into the machine is converted into useful work output without any loss of energy due to friction or other factors.
Work output divided by Work input Times 100
In that case, the efficiency is said to be 1 - or equivalently, 100%.
To calculate the efficiency of a machine, you would need information such as the input work or energy applied to the machine and the output work or energy generated by the machine. Efficiency is typically calculated by dividing the output work or energy by the input work or energy and multiplying by 100 to express it as a percentage.
