When I got home very early this morning, I learned some highly unpleasant things about a typical door on a typical two-car garage:
- There is a very large spring that keeps it balanced such that a relatively low horsepower electric motor can raise and lower it
- When that spring breaks, the door weighs eight hundred million pounds.
- A 1/3 horsepower electric motor cannot raise, unassisted, an eight hundred million pound door.
- A typical male of average strength can only just barely raise, unassisted, an un-sprungĀ two-car garage door to free his wife’s car–without passing out.
- I think I seriously injured myself getting the garage door open.
I’m actually glad I discovered this at 2:00am and not Butterfly at 700 am, as she would be late taking T-Rex to school and getting to work.
I’m going to go medicate myself and lie down now.
