No. The machine can multiply input force if it's built to do that. But when it does,
it divides the distance by the same amount. So the product of (force x distance)
comes out the same as what went in. The product of (force x distance) is the input
work, or energy, so that doesn't change.
(In fact, some of it is always lost going through the machine, so what comes out
is always a little less than what went it.)
What else can I help you with?
What does a machine not do multiply force multiply energy change direction of a force or work?
Does not multiply energy. Work done or energy used (force * distance) remains the same at both ends. Force or torque can be increased or decreased depending on mechanical advantage. It can change the direction of the force or torque.
What is the work input for a machine?
The work input for a machine is the amount of energy or force that is put into the machine in order to make it operate. It is the energy that is required to do work on the machine and make it perform its intended function.
What is a comparison of a machines work input and work output?
mechanical efficiency
Why is it impossible for the output work of a machine to be greater than the machine's input work?
The output work of a machine can never be greater than the input work because of the law of conservation of energy, which states that energy cannot be created or destroyed in an isolated system. Any energy input into a machine must be accounted for in the output work, so the output work cannot exceed the input work.
If the input work on a machine is equal to its out put the machine has what efficiency?
The machine would have 100% efficiency if the input work is equal to its output. This means that all the input energy is fully converted into useful output energy without any loss.

What information would you use to calculate the efficiency of a machine?
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.
What energy that put the amount of work machine?
The energy required to perform work in a machine is typically sourced from a power input, which could be electricity, fuel, or some other form of energy input. This energy is converted by the machine into mechanical work through various mechanisms such as electrical motors, combustion engines, or hydraulic systems. The efficiency of the machine determines how much of the input energy is successfully converted into useful work output.
What is the efficiency of a machine that requires 120J of input energy to do 35 J of useful work?
The idea is to divide the useful work by the input energy.
How is the efficiency of a compound machine calculated?
The efficiency of a compound machine is calculated by dividing the output work of the machine by the input work. Mathematically, it can be expressed as Efficiency = (Output work / Input work) * 100%. It gives a measure of how well the machine converts input work into useful output work.
What must you know in order to calculate a machine's efficiency?
The efficiency tells you how good the machine is. Efficiency equals the power output of the machine divided by the power that is input via a shaft, or via electrical wires, or via fuel. So if the machine has a low efficiency it wastes power and energy, which costs money. The average ordinary automobile has an efficiency of 20-25%. A lot of research work goes into improving that figure.
In a machine work output is less than work input because some energy is converted into thermal energy True or false?
True. In a machine, not all of the input work is converted into useful output work. Some of the input work is lost as thermal energy due to friction, inefficiencies, and other factors. This is why the output work is always less than the input work.
