I was wondering if someone could give me a little clarity here. If using gears to reduce a servo's / motor's rotation by 50%, will that increase it's torque per cm?
I'm going to be using a 40kg servo and I am going to reduce its rotation from 210 degrees to 105.

I will try and find a link or two unless someone else does it first.

This is a good one. Link2
So, in this case, to move 105 degrees will take twice as long as before since the servo horn needs to turn the full 210 degrees still. And the torque will be 80kg/cm (less gearbox losses).
I have assumed it follows the same laws of physics and principals as anything else however please feel free to double check and wait for other input on the subject.

Puzzled....
@Jaychandw, it'll come back to you. It took a few weeks for my electronics knowledge to flood back to me when I hadn't used it for 15+ years.
This doesn't under mind others answers I just put a "simple" one out there.
Thanks for that guys it really helps.
@everyone I am remembering bits and bats, getting the confirmation really helps. Thanks for he support. I just wish it'd come back quicker *stress*
@jstarne I'm definitely going to remember that in my calculations, reduce by 15%
@Troy Thanks for those links, immensely useful.
