Lift a Car With One Hand

Pulleys spread a heavy load across many ropes

Could you lift a car with one hand? With enough pulleys, the pull gets surprisingly small. So where does the missing effort go?

You'll find out

  • Why one pulley isn't enough
  • What you pay for an easy pull
  • What real pulleys lose

Why it matters

Every block and tackle trades a long pull for a light one. Knowing the trade shows why nothing comes for free.
