Based on a physics textbook, TORQUE is defined as a cross product between Force and Distance (T = F x D).

Scenario:
Given: a circular disc with a radius of 2 feet that is connected to a shaft (making them a single unit).

Question:
If the shaft is rotated with a Force of 10 pounds, and the edge of the disc is attached to another another disc with a similar shaft, what would be the output torque? 20 lb-ft? Please explain.

A simple illustration below. The figure represents the 2 discs with shafts (face opposite each other).

Force 10 lbs... --[ ]-- ...Torque at the other end?


Many thanks!

As most of the countries talk about planting tress and other methodologies
To reduce the effect of global warming, why can’t we genetically modify a
Tree/plant so that it bears leaves of very huge size, which inturn facilitate it to absorb or capture more
Carbon dioxide. Is this technique possible ?
