Just wanted to know some of your favorite physics and math equasions during build seasions thanks.

One I thought about when I was a Junior in high school

F=ma, right?

Work = Fd, agreed?

So,

work is mad

(This is one of those times I wish the “therefore symbol” was on the keyboard - you know, the three dots that form a triangle.)

While programming a crab drive back in 2009, the arctangent function was my friend. Then sin and cos became my friends too. Sooo much math in 4-wheel independent steer independent drive crab drives.

so far mine has been nested if statements with nested statements in them

we did this for our arm

3 hours of programing and only 10 lines of code

Work is force/distance

don’t mean to be rude just wanted to help

How can you go a day through life without using these babies:

-PV=nRT

-sin, cos, tan, sec, csc, cot

-F=ma

-W=FD

-t=Fr

-P=W/T

-All unit conversions (although annoying. All for the metric system say “I”)

You are right about the formulas

Work is force/distance

I don’t mean to be correct, but check again

W=Fd

(lowercase) tau = I*omega (lowercase)

P = IV

GP + Fun = WIN!!!

its force x distance, he had it right. the full equation is technically F(D)cos(theta)

You don’t have a ∴ key? It’s right next to ‘Any’ key.

…which is right next to the Easy Button…

…which is right next to the “compile faster” button…

T = ((et)^5) + 7s

Give up? Hint. et is estimated time, T is actual time. s is the number of times you say it’ll be easy.

So if I say it will take half a minute, then it will actually take one thirty-second of a minute, assuming I don’t say it will be easy at all?

Idk, but the Law of Cosines has become more sexy than usual…

Internet + Cats = Robot that doesn’t work and isn’t built.

Most Used: (Machine Shop Algebra for finding the coordinates for paired symmetrical holes on material. With d1 being the material length, d2 being the hole pattern, and x being the distance from the hole center to the edge of the material)

**x = (d1/2)-(d2/2) = (d1-d2)/2**

Most Reliable: **Newton’s Second Law**

Least Favorite: **Murphys Law**

I’ve been modelling some of our robot’s movements using an intersection of two circles…

(x-a)^2 + (y-b)^2 = r^2

It is ftw

Can’t believe no has said this yet:

V = IR

(I^2)R = VI = P

Or, to have some fun:

Fs >= 2B (any takers? it’s not an exact formula, more of a theorem, and kind of hard to represent without proper math symbols)
