Computing Strain

AI Thread Summary

To calculate lateral strain from diameter changes, the formula Δd/d is used, where Δd represents the change in diameter and d is the initial diameter. This approach focuses on the direct relationship between diameter changes and lateral strain. While some may consider using area changes (ΔA/A), the discussion emphasizes that the diameter-based formula is more straightforward for this calculation. Understanding lateral strain is crucial for applications involving material deformation. Accurate calculations are essential for engineering and material science applications.

I'm trying to compute lateral strain for a bar (strain that would make it thicker, or have more cross sectional area).

All I know are the initial and final diameters. This gives me d1 and Δd.

Would the lateral strain be Δd/d or ΔA/A? (A is area)

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

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...

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...
