For a project in my 3rd year hydraulics course we have to design a water distribution network for a residential area using EPANET and optimizing it using GAWUP (GANEO). I have the entire network set up with all the peak flow demands set for each of the required nodes. Using GANEO I can easily...

I just realized that using a tube to measure the torque of a motor with propeller will result in an axial tension in the tube as well as shear. The strain gauges aligned at 45 degrees on the fixed shaft to obtain the strain due to principal stresses will no longer be just due to the torque of...

I posted another thread here talking about two instrument designs using strain gauges. One was for measuring torque, and the other for acceleration. I would like to go ahead with designing an accelerometer using a full strain gauge bridge. The basic idea I have in mind is similar to this...

The reason why I wanted to go ahead with a tube is to obtain more strain, and therefore better sensitivity. Remember, I am trying to measure the torque produced by a relatively small motor and propeller. That is the trick with this instrument design. The max specified mass of the instrument is 5...

Alright, since the motor will be spinning, I am guessing the torsion developed in the fixed shaft will give me the dynamic torque value of the motor and propeller ? Also, as far as I know, it should be possible to use a fixed tube, instead of a solid shaft, to measure the strain since the max...

I am busy studying engineering and I have a subject that requires us to design and build a working instrument using strain gauges. We have a workshop at our disposal and all necessary materials and electronics. At this moment my group and I are stuck with coming up with an idea for an...
