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

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
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 'Turbocharging carbureted petrol 2 stroke engines'
Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...
