Planar load cell arrangement
1.5mm thick steel 5kg load cells are sandwiched at corners of two aluminium plates.
As the load cells are rigidly mounted, would the deflection shape of the load cell bending element represent a step ...

Is there any force/torque sensor that can determine the net force producing the strain, irrespective of the point of application?
I would like to measure the weight of something that hangs off a cantilever beam. My idea would be to put some sort of force sensor in the beam's anchor point, but a simple strain gague won't do, I ...

3 axis load cell geometry
As far as I'm aware, there are two main types of 3 axis load cells.
The first type is simply similar to joining 3 single axis cells by their ends, each pointing in a different axis, like so:
(Source)...

Is it possible to simulate inertial load using brake?
Suppose to have an engine attached to a flywheel, I add power, the flywheel start to rotate and oppose a resistance to motion. More power, more resistance.
I'm wondering if I can simulate this ...

How do I relate tongue weight to weight x distance?
The specification for car hitches routinely state the tongue weight, but do not specify how far that weight can/should be applied. What am I missing? Shouldn't the maximum bending moment be the one to ...

Distributing force / load across two measurement devices (load cells)
I am looking to measure the force applied (in this case by a foot to a pedal).
I have a working prototype that allows up to 450N of force, but wish to double this.
The load cell I have been using is ...
