AI Thread Summary
The discussion revolves around calculating moments for a small portable crane designed to retrieve a 200 lb sediment grab from a depth of 50 meters on a boat. Participants suggest starting with static analysis to determine the crane's stability and load distribution. There is a request for sharing results, diagrams, and any concerns or unusual values encountered during the analysis. The focus is on ensuring the crane can safely handle the specified weight and depth. Effective calculations are crucial for the crane's design and operational safety.

building a small portable crane to be used on a small boat that will be used to retrieve a sediment grab (weight = 200lb) at a depth of 50m

Have you tried using static analysis as a starting point?
 
yes i have
 
So...any results? Diagrams? Concerns? Questions? Values that might be weird?
 
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...
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...
