What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
How do you calculate the efficiency of a machine?
Efficiency is nothing but calculating how the machine is performing for what it has been made for, Efficiency is usually calculated in % as (output/input )X100. for Eg. the Thermal efficiency of an reciprocating gasoline engine can be calculated as follows, Let, the input for an reciprocating engine is 12MJ and its out put is 4MJ then Efficiency is (4/12)X100 = 33%
Why cant a machine be one hundred percent affective?
The reason why amachine cant be one hundred percent effective is as a result of losses.For Electrical machine such as alternator we have Mechanical losses(such as windage and frictional losses)and Electrical losses(such as copper loss in the rotor winding and stator winding).In Mechanical machine the main losses are windage and frictional losses.NOTE;ALL THIS LOSSES RESULT IN THE PRODUCTION OF HEAT,THUS REDUCING THE EFFICIENCY OF THE MACHINE.
What is the full form of mpm as unit?
Mechanical pnematic machine
What do you call the number of times a machine multiplies the force?
That's the "mechanical advantage" of the machine.
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
What is mechanical efficiency in science?
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
What is used to calculate mechanical efficiency?
work
What is the mechanical efficiency of a machine that produces 400 joules of work output from work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
What is mechanical in science?
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
What would a machine that had 100 percent mechanical efficiency be called?
A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.
What must you know in order to calculate a machine's efficiency?
To calculate a machine's efficiency, you need to know the input energy (such as electrical or mechanical energy supplied to the machine) and the output energy (work done by the machine). Efficiency is calculated by dividing the output energy by the input energy and multiplying by 100 to express it as a percentage.
What is the mechanical efficiency of a machine whose work input is 100 J and work out put is 30 J?
The mechanical efficiency can be calculated using the formula: Efficiency = (Work output / Work input) * 100%. Given the values, we have: Efficiency = (30 J / 100 J) * 100% = 30%. Therefore, the mechanical efficiency of the machine is 30%.
What is the mechanical efficiency of a machine that produces 400 joules or work output from a work input of 500 joules?
The mechanical efficiency can be calculated as the ratio of work output to work input, multiplied by 100%. In this case, the efficiency would be (400/500) * 100% = 80%. So, the mechanical efficiency of the machine is 80%.
What would be the mechanical efficiency as a percentageof a machine that produced an output of 200J with an input of 250J?
The mechanical efficiency of the machine is calculated by dividing the output work by the input work and multiplying by 100 to express it as a percentage. For this scenario, the mechanical efficiency would be (200J/250J) * 100 = 80%.
What role does friction have in reducing mechanical efficiency?
Friction is the reason that you can never have a 100% efficient machine. It is the reason that most machine have horrible efficiency.
How do you calculate the capacity of a machine using formula?
how to calculate the embroidery machine capacity and Embroidery factory capacity and efficiency.
