Can anyone give me some insight into the fracture mechanism of these 2 bolts?
I know what they came out of and ultimately what caused them to break, just curious as to others thoughts about the process.
They are 5/8th UNC Gr8 bolts and were in single shear but had support blocks to prevent shear load.
Finally seeing some good press for Liam in r/formula1
He has driven sensibly and well and it's finally getting good recognition. Slow and steady is starting to win the race.
Found this in the wild tonight. GS850G With an S fairing and an air cooled RM500 motor, shoehorned into a 250 frame. All this on a side car. What a beauty.
My thought for the day is, business think they are exempt from the enshitification of Internet products and eventually they will realise, that they have laid off their staff to be replaced by AI and once they are captive, will pay more for their subscription for AI, than they were for their staff they laid off.
Big change blowing in, lower North Island NZ.
Curious as to what these formations are.
Beautiful looking sky.
OK, not exactly auto but I have an automatic gate that operates on 24 VDC. It runs from two 7.5 AH batteries (alarm panel batteries). It has a trickle charger, supplied from 240 Vac but that definitely only supplies charging. The gate opener (linear actuator), runs straight from the batteries.
This has run fine for 14 months but has just recently, started to only partially open in the mornings. For context, we are just starting our autumn and have already had a mild frost.
I can apply some minor assistance manually, and it will then continue to open by itself. By 9 Am, the gate is opening unassisted , albeit a bit sluggish.
I checked battery voltage this arvo and had 26.5 volts, measured in series. Separating the two gave pretty balanced readings as well.
Checking voltage while operating the first time, gave a voltage drop down to around 25.5 v. No sign of mechanical issues, pivot, hinges all free.
Operate again, a couple of times in reasonable quick succession and suddenly seeing voltage drop to 20 v and less.
Voltage would restore within 5 secs or so, to 25.5 v. (yes, I should have checked this without the trickle charger still connected but didn't).
Does that sound like failed batteries or should I look more closely at the current draw on the actuator?
Grew some Kumara in one of those little plastic tubs this year. Pleasantly surprised with the harvest.
