AI Thread Summary
The discussion centers on confusion regarding calculating the lengths of beams in a cantilever framework practice exam. A participant suggests using a Free Body Diagram (FBD) to analyze the forces instead of needing initial lengths. They explain that the reaction forces can be represented with blue and red lines in the diagram. The key equations to apply are the sum of vertical and horizontal forces equaling zero. This approach simplifies the problem and clarifies the necessary calculations.

You don't need them. Just do a FBD and you will see.
I started it for you. The blue lines are the reaction forces in the beams and the red lines are the components of the reaction force of the slanted beam. Sum of Fy = 0, sum of Fx = 0 ...

Ah thanks for that, much appreciated! Knew I was missing something.jack action said:
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.

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
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
