Title text:
It's hard to decide which simple machine system to invest in. DeWalt makes a great lever and inclined plane, but I hear Milwaukee's wheel-and-axles are really good.

I used a wedge and hammer last night to split one very large limestone block into 5 more manageable ones and I've never felt more ancient Egyptian in my life.
I seem to remember wedge was basically an inclined plane, and a screw was an inclined plane wrapped around an axle. Also a pulley is a specific application of wheel and axle.
But is a lever an adjustable inclined plane, or is it a specific application of a wheel and axel?
Is it all inclined planes????

Arenβt scrwws just a fancy inclined plane?
Screws convert rotational energy into directional energy
TIL the definition of simple machine.
