Learning objective
Explain mechanical engineering, reproduce the worked example and justify a decision in the case study.
Before you begin
Civil engineering
Understand
Mechanical engineering studies forces, motion, energy, heat, machines, and manufacturing.
Worked example
A lever trades distance for force around a pivot.
Analysis and common mistakes
For an ideal balanced lever, force × distance from the pivot is equal on both sides. Force advantage generally requires greater movement; friction reduces real efficiency.
Case study — reasoning
A 100 N load at 0.2 m balances 20 N at 1 m: 100 × 0.2 = 20 × 1. Equal moments do not create free energy.
