    Force Table
AI Thread Summary
The discussion centers on whether a shaft with two cylinders, each applying 300 pounds of force, exerts a total of 600 pounds of force on the table. The basic principle of statics is referenced, indicating that the sum of vertical forces must equal zero. If both cylinders are indeed applying force simultaneously, the total force exerted on the table would be 600 pounds. The conversation emphasizes understanding basic load calculations without considering moments. Ultimately, the conclusion is that the shaft applies 600 pounds of force to the table.

I have a shaft laying across a table. At each end of the shaft I have a cylinder. Each cylinder is capable of appling 300 pounds of force. My question is; Is the shaft applying 600 pounds of force to the table or just 300?

Looking at the most basic load, i.e. no moments...600 pounds force (assuming both cylinders are applying a force).

Basic statics: \Sigma F_y = 0
 
Thanks for the quick response and help.
 

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...
