AI Thread Summary
A linear regulator can effectively control a 24V and 12V system if the output voltage is allowed to be a couple of volts lower than the input. This approach is suitable for applications where precise voltage regulation is needed, but efficiency may be compromised due to heat dissipation. For a frac company's trucks, maintaining steady voltage levels is crucial for electronics performance. However, if higher efficiency is required, a switching power supply may be a better alternative. Overall, the choice between a linear regulator and a switching power supply depends on the specific voltage regulation needs and efficiency considerations.

I work in the Oil Field for a frac company, our trucks run a 24v and 12 v sytem,I'am looking for a way to regulate the 24 and 12 coming into the electronics from the power box to hold a stedly 24 and 12 volts.

Switching power supply.

If you can tolerate it being regulated to a couple of volts lower than the input, then you could use a linear regulator.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

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 '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...
