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 '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 'Calculate minimum RPM to self-balance a CMG on two legs'

Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...

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...
