    Piston Spring
AI Thread Summary
To calculate the torque of a spring-actioned piston when the spring is released, two key equations are necessary. The first is Hook's Law, which relates the force exerted by the spring to its compression. The second equation can be derived from a free body diagram, illustrating how the force from the spring translates into torque on the wheel based on the wheel's angular displacement. Understanding these principles will enable accurate torque calculations. This approach provides a foundational understanding for solving the problem presented.

hi guys, this is my first post (and i am don't know much physics), i have a problem that I've ilustrated in a drawing that i attach to this post. Ok so it goes something like this ... if the spring is compressed manually , when i release it how do i calculate the torque of the wheel?
this is the link to the drawing :

can some1 help me with this problem??
 
Two equations will be most useful to you. One will be simple Hook's law for the spring. The other you can derive from a simple free body diagram, to show how force at the spring converts to torque to the wheel as a function of angular displacement of the wheel.
 

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?'

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...
