How do I calculate torque on a beam with two antiparallel forces on both ends?

« on: 10/08/2017 16:45:56 »

Hi all...

I'm experimenting in using single point beam load cell as a dynamic torquemeter (picture below). I already get the equation for strain, but i'm confused how to get torque value from that strain?
Most existing equation is for cantilever beam, but i think my project isn't cantilever beam cause both ends have forces working on it.

Please help me...

For the uninitiated a dummies.com torque brush up.

Even the most obstinately ignorant cannot avoid learning when in an environment that educates.

A torque strain calculator may be a good place to start.
