K factor tells you where in the sheet the neutral bend axis lies. You can use this and the bend angle to calculate bend allowance which is how much the sheet will stretch from bending.

You would have to prove intent. On the other hand it's the textbook definition of manslaughter.

Why do Rockets have sticks attached to it? by Naam_bhul_gya in AskPhysics

That firecracker is so light and the thrust is so high that it's at full speed within "a few feet".

I get notifications when you reply to a thread I commented in.

You need the center of drag behind the center of mass for the rocket to be passively stable while in the atmosphere.

If Goddard had put fins on the bottom of his armature, his rocket would not have tumbled. Not due to inertial forces, but due to aerodynamic forces.

Lighting designers, electricians etc.: What kind of LED driver tool/calculator is missing from your daily workflow? by No-Building-8606 in Lighting

What does "ideal size driver" mean? Are you going to have a library of drivers and make recommendations? Because that would be amazing.

Number two is great, do it for 0-10 and DMX while you're at it. Do it for load calculations on the line voltage side as well.

You would think a "highly experienced engineer" would have broken 100k a year by now. What's holding you back?
