Torque Question for Boffins
Anyone have a calculation I could use to calculate torque applied using a
lever of length x and load of y grammes ?
It's for a physics lesson thing.

Yeah, torque in Newton-Metres is Load in Newtons x Length in metres (surprisingly )
1 Newton is 102 grammes so:
Torque = Mass(g) x Length(m) / 102
Hope this helps...
Matt.

Torque is force x distance x sin(angle)
SO at 90 degrees the torque eg of 1 kilo at 1metre from fulcrum is 1 x 1 x sin(90) = 1NM. Torque decreases with sin as angle changes.

That would actually be 1kgm = 9.81Nm.
Good point about the angle though.
Cheers,
Matt.

Depends what planet you're on. I was working on the assumption of a planet slightly larger than earth where 1Kg exherts 1N 
You were indeed correct to point out my c0ck up tho!

Gravity varies with altitude and latitude. Find yourself a nice below-sea-level valley away from the equator and your 1kg = 1N fantasy might come
true!

Also depends on underlying rock.

anyway its the reason
i wanted a transmission box because my prop had quet some angle
20 / 30 degrees.
Tks
