Can anyone decipher this scribble? Found it in my late father's jacket. https://counter.social/media/yyYbPV5oOUy9eiR0IAI
@Blackwolf looks like solving for force, f=kx is Hookes law. There's other stuff there, be interesting to know his job.
@StevenH Knowing my dad it's more like how to bet on horses lol
@Blackwolf can't stop coming back to this and trying too figure out where it starts. From the various angles it looks like a scrap paper with many different questions scribbled across it whenever it was pulled out.
@StevenH it's on an index card and yes, it's probably several ideas on one card :)
@Blackwolf it's not really a math I'm good at, but I'd make a guess it's some back of napkin equations for car suspension systems.
