Calculating Torque using Steiner Theorem?

AI Thread Summary
When calculating torque for structural analysis of a wing, the upward shear force or lift acts at the aerodynamic center (a.c.). It's important to consider the moment about the a.c. when calculating torque about the shear center, which coincides with the a.c. The discussion emphasizes the application of Steiner's theorem in this context. Properly accounting for these moments is crucial for accurate torque calculations. Understanding the relationship between the shear center and aerodynamic center is essential for effective structural analysis.

I am going to do some structural analysis of the wing. The upward shear force, or lift, is acting at the aerodynamic center. There is also a moment about the a.c. I am just wondering if I need to take the moment relative to the aerodynamic center into account when I calculate the torque about the shear center?

The shear center is in the a.c.
Use the Steiner theorem.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
