Forces on Equilateral triangle truss

AI Thread Summary
The discussion focuses on analyzing the forces acting on an equilateral triangle truss with a known force F applied at the top in the x direction. The user has calculated moments at both supports to be (½)F and determined that member AD experiences a force equal to F, while member AB is calculated to have zero force. The inquiry seeks validation of these findings and requests others to share their calculations for better understanding. Clarification on the reasoning behind the zero force in member AB is also sought. The conversation emphasizes the importance of showing work to facilitate collaborative problem-solving.

Hey Guys,

My question involves finding all of the forces acting upon each member. It is known that each side of the triangle has a length of l. It is also known that the force is acting at the very top of the triangle in the x direction (to the right) labelled as F.

Attempt:
I found moments at both supports (bottom left + bottom right) to be (½)F. I have found that AD = F and for some reason AB = 0?

Is this incorrect?

How about showing the work you have done so we can see how you are thinking? That would help a lot.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

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 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
