Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.

Can any pulley have a efficiency over 100?
No. A perfectly frictionless machine could have an efficiency of 100%. Anything less perfect must have can efficiency less than 100%.
How do you calculate the capacity of a machine using formula?
how to calculate the embroidery machine capacity and Embroidery factory capacity and efficiency.
What is the Maximum efficiency machine?
The electric space heater. It's the only common machine that's 100% efficient.
What is the mechanical efficiency of a machine that produce 400 joules of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
How do you increase a Thermal efficiency of brayton cycle?
by increasing the turbine inlet gas temperature
How does the work done a machine compare to the work done by a machine?
The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.
A machine has an efficiency of 70 percent how much work does the machine do when 20000 J of work is done on it?
If the machine has an efficiency of 70%, it means that it only converts 70% of the input energy into useful work. Therefore, the work done by the machine would be 70% of the 20000 J of work done on it, which is 0.7 * 20000 J = 14000 J.
Which factor increases as the efficiency of a machine increases?
The output work done by the machine increases as the efficiency of the machine increases. This is because efficiency is the ratio of useful work output to the total work input, so as efficiency increases, more of the input work is converted into useful output work.
How does input work and out put work affect the efficiency of a simple machine?
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.
How do you determine machine efficiency?
Machine efficiency is typically determined by calculating the ratio of useful output to input. This can be done by comparing the actual output of the machine to its theoretical maximum output under ideal conditions. Factors such as energy losses, downtime, and maintenance can also affect machine efficiency.
Why does reducing the friction of a machine increase it's efficiency?
Reducing friction in a machine decreases the amount of energy lost as heat, making the machine more efficient. This means that more of the input energy is converted into useful work or output, increasing the overall efficiency of the machine.
Formula to calculate work efficiency?
efficiency formula is (Wout/Win)*100% Wout is the work done by the machine is called the output work Win is the work done by you on a machine is called the input work efficiency= useful work output/work input For science, the effiency is: AMA/IMA * 100
Does a machine with an efficiency of 1.2 requires a smaller effort force than a machine that has an efficiency of 2.2?
No, the efficiency of a machine does not directly correlate with the effort force required. Efficiency is a measure of how well a machine converts input work to output work, but the effort force needed depends on factors like the load being lifted and the mechanical advantage of the machine.
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 increases the work output of a simple machine?
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.
What happens if you increase the efficiency of a simple machine?
Increasing the efficiency of a simple machine means that it requires less input work to produce the same output work. This results in less wasted energy and ultimately allows the machine to do more work with the same amount of input.
Can a machine increase distance?
Yes, a machine can be used to increase distance through its mechanical efficiency and power. For example, a vehicle can cover longer distances in a shorter time compared to walking.
