Does a machine with an efficiency of 1.2 requires a smaller effort force than a machine that has an efficiency of 2.2?
Efficiency is a measure of power losses. A machine with an efficiency of say 85%
or 0.85, experiences 15% power losses from input to output (as heat through friction)
This would be typical for say a car, comparing crankshaft power to power at the drive wheels.
No machine will exceed 100% efficiency

Work done = force * distance
Efficiency = work done at output / work done at input
>
Mechanical Advantage (leverage) is distance moved by input / distance moved by output.
Output force = input force * Mechanical Advantage

How well a machine changes effort into work?
The efficiency of a machine in converting effort into work is determined by its mechanical advantage and the energy losses during operation. A higher mechanical advantage indicates better efficiency in converting input force into output force. Minimizing losses such as friction, heat, and noise can also improve the overall efficiency of a machine in converting effort into work.
In a machine the effort force you apply is used to overcome a?
In a machine, the effort force you apply is used to overcome a resistance force, such as the force of friction, gravity, or inertia. The goal of the machine is to make it easier for you to move or lift objects by increasing efficiency or changing the direction of the force applied.
What is the effort in a simple machine?
Effort in a simple machine refers to the force applied by a person or machine to operate the machine. It is the input force needed to overcome resistance and move the load in the machine. The effort required depends on the type of machine and the mechanical advantage it provides.
How do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
To calculate the effort required, first determine the input force needed to lift the load by dividing the load (300N) by the mechanical advantage (velocity ratio of 5). So, 300N / 5 = 60N. Next, take into account the efficiency of 60%, so the effort required is 60N / 0.60 = 100N.
The efficiency of a real machine?
Efficiency is equal to the ratio of work input to work output; for an ideal machine this ratio is equal to 1 or 100%. For a real machine this ratio is always less than 1 because some of the work input is used to overcome mechanical friction within the machine which does not contribute to the work output of the machine.

What is velocity ratio?
Velocity ratio is the ratio of the distance moved by the effort to the distance moved by the load in a simple machine. It represents the trade-off between force and distance in a machine. A higher velocity ratio indicates that the machine can move the load a greater distance with a smaller input force.
How does reducing friction increase the mechanical efficiency of a compound machine?
Reducing friction in a compound machine helps minimize energy loss due to heat and wear, improving the overall mechanical efficiency. With less friction, there is less resistance to the movement of parts within the machine, allowing it to operate more smoothly and with less effort. This results in increased performance and reduced energy consumption.
Will a machine save work or always waste work?
A machine can save work by automating tasks, improving efficiency, and reducing human effort. However, if not properly maintained or used incorrectly, a machine can also waste work by breaking down, causing errors, or requiring frequent repair.
A simple machine consisting of two circular objects of different sizes?
That’s a wheel and axle! It’s a simple machine where a big wheel and a smaller axle work together to make tasks easier by reducing effort.
What two things must the effort force applied to a machine do?
The two things are momentum and acceleration when the effort force is applied to a machine
Why does pulling a load up requires more effort?
it requires more energy to pull because the load is heavier than the effort.
What is Effort?
THE FORCE APLIED ON A MACHINE FOR DOING WORK IS CALLED EFFORT IT IS REPRESENTED BY (E)
