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.
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?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N
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
The mechanical what of a machine compares the input force with the output force?
Mechanical efficiency
What would a machine that had 100 percent mechanical efficiency be called?
an ideal machine
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
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 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.
The amount by which a machine multiplies an input force is called?
mechanical advantage
How do you calculate the efficiency of vapour absorption machine?
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
What can be done to increase the efficiency of the machine?
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.
