Does anybody have a table of coke or charcoal burn rates?
In air. This seems like it should be incredibly basic information but I can't find it anywhere.
Building a DIY solar panel mount: how would I calculate the parameters for a linear actuator to tilt the panels between completely horizontal and vertical?
I'm trying to figure out how long to make A and B here if I have linear actuator of length C (extended = 2C) in order to tilt my panels from completely horizontal to vertical so they avoid wind and shed snow respectively when I run up the actuator to the extremes respectively based on sensor input.
Is there a simple formula I can use to plug the length of whatever actuator I settle on to figure A and B out? I know it will have to be a certain minimum and maximum size to work properly and might have to experiment to get an idea of what works in the end, but I'd like a reasonable start point to purchase an appropriate actuator.
I've googled around and decided I'm not smart enough to even come up with the right search criteria, let alone figure this out myself since it's been 35 years since I've used anything except the most basic trig.
This isn't really homework except for the fact that I'm trying to make my home work right.
Edit: seems like if I select A=.75C and solve for B at horizontal, then it always works out. No idea why, but the couple examples I try seem to agree.
Need some advice on creating a waterproof container that allows for a sliding stainless steel rod
Hello lemgineers!
I'm working on designing a claw that can be operated underwater. The plan is to use a linear actuator in a waterproof housing. The main issue is allowing the shaft to slide through without causing a leak. What's the best way to go about this?

Since the early 2000s, wind turbines have grown in size—in both height and blade lengths—and generate more energy. What’s driving this growth? Let’s take a closer look.
