Question

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