What is the mathematical representation of a machine's efficiency? (1 point)

Question

Responses

Efficiency = EiEo
100
Efficiency = cap e i over cap e o100

Efficiency = EiEo
Efficiency = cap e i over cap e o

Efficiency = EoEi
100
Efficiency = cap e o over cap e i100

Efficiency = EoEi100

Answer 1

The mathematical representation of a machine's efficiency is:

Efficiency = (Eo / Ei) * 100

Where:

• \( Eo \) = output energy or work
• \( Ei \) = input energy or work

This formula represents the percentage of input energy that is converted into useful output energy.
