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 difference between real mechanical advantage and speed ratio?
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
The mechanical what of a machine compares the input force with the output force?
Mechanical efficiency
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
What is the term for the comparison of input and output work of a machine?
Sounds like you are asking about "mechanical advantage"...
What is used to calculate mechanical efficiency?
work
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
How do you calculate the mechanical efficiency of a machine?
Work output divided by Work input Times 100
How do you calculate the efficiency of an electrical mechanical system?
You could have an electric motor driving a reduction gearbox, for example. The efficiencies of both might be considered individually, or as a whole. As a whole is easier. (Work out/ work in) x 100 = efficiency%. Or, (power out/ power in) x 100 = efficiency%. Or, (force out/ force in) x100 = efficiency%. It depends on what you have to work with, what you use. If you did need to calculate electrical and mechanical efficiencies separately because of different units, the final overall efficiency will be (total of the percentages) / (number of percentages).
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 the formula to find mechanical efficiency?
Mechanical efficiency = (output energy)/(input energy) . It's typically stated as a percentage.
What is the difference between real mechanical advantage and speed ratio?
the difference between the real mechanical advantage and the speed ratio is -the real mechanical advantage gets affected by friction so the real mechanical advantage gets smaller than the mechanical advantage you calculate. so the real mechanical advantage gets smaller than the speed ratio (because of the friction) and that's why the efficiency never gets 100% efficient (efficiency ; mechanical advantage/ speed ratio x 100(%))
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 measure efficiency?
Efficiency= Mechanical Advantage Speed ratio X100 Mechanical advantage divided by speed radio X (times) 100
The mechanical what of a machine compares the input force with the output force?
Mechanical efficiency
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
Which Mechanical efficiency has efficiency100 percent?
watches
