Is Beam Deflection Indicated as North or South Using the Macaulay Method?

AI Thread Summary
In beam deflection analysis using the Macaulay method, a positive deflection value typically indicates upward deflection, while a negative value suggests downward deflection. The direction of deflection can also depend on the placement of loads along the beam. For example, if the calculated deflection is 1.9mm, it would generally imply an upward movement unless specified otherwise. Confusion may arise when multiple loads are present, as their effects can influence the overall deflection direction. Understanding the load distribution is crucial for accurately interpreting deflection results.

Hi, quick question

Ive been using the beam deflection forumla EIV=...

and I am getting answers of 1.9mm for example

does this mean that the deflection is in the south direction or north?

Cheers

Surely you can figure this out based on where the load is placed?
 
yeah i know but I am just getting confused cause there's more than one load
 
febbie22: Using the Macaulay method, positive answers usually mean upward deflection.

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

Thread 'What's the most likely cause for this carbon seal crack?'

Thread 'What's the most likely cause for this carbon seal crack?'

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...
