Thank you for the suggestion

I have two questions: 1) Is it possible to cut the material with a laser cutter or scissors or do I need to have a specific tool? 2) What is the best way to attach the PZT-5H material to the beam but it can be easily detached for using it on another beam ( so no epoxy glue)?Thank you

Thank you so much

This data is on Bimorph beam (PEH)...

Ps: It is not a homework hence why I did not leave it under that headline.

Thank you so much

I ignored a negative sign in my analytical calculation, this is why I had two values in the opposite direction.

I managed to find the error. Thank you.

This is the analytical working out. I substituted the value of 306mm ( the maximum length of the beam) to find the maximum deflection along the Z-axis. Which came out to be -2.39mm. But according to Ansys the average deflection is 0.3mm and the maximum deflection is 0.8mm. This is the Ansys Values.

Hi Berkeman and @Lnewqban, I have taken all your advice into account and slightly modified the design to minimise the bearing friction, I have increased the diameter of the second stage pulley and also introduced another pulley in the first stage to decrease the friction. I am learning a lot...

Thank you so much for your help.

Do you think this cable arrangment will cause the elevation. I still have not considered about the co-axial design to decrease the bearing friction.

This is the sketch from the video, later in the video he replaces the pulley with a screw eye hook, I think that's is why he didn't have another hook in stage two.

Thank you for all your responses. I used this sketch to design my mechanism. Furthemore, would I be able to use this to find the torque.
