Hello,

I realize that this is a Physics 101 pop quiz problem, but it's been 45 years since I was in Physics 101

I'm trying to figure out what size of a 12VDC motor to purchase to perform the following work.

I have a 40 Kg tool that I want to lift 30cm within 60 seconds.

If you need the length of a lever arm to calculate this, then assume a gear wheel of 2.5 cm in diameter.

Any help would be appreciated.

Thanks,

John
