I thought of another way to remember the equations: "I got a sick sister, cuz; with THoes (toes) and PHIet (feet) too" SIC -- Sin Cos for X SIS -- Sin Sin for Y COS -- Cos for Z THoes and PHIet -- angle theta goes before angle phi (theta is alone in F_z) Hope this helps.

@@Error-br1uy it’s a weird one to get your head wrapped around at first, but the main thing is to just follow your rules and think about things logically in a step by step way. I think statics looks scarier than it actually is because once you start breaking things down things start to click.

@jonathansanchez2854 Жыл бұрын

Question, so you know how in 2D system, Fx is not always sin but it can also be cos and Fy is not always cos it can also be sin. Here in 3D system will be Fx always be Fcos(swing angle)sin(thetaz) and Fy be Fsin(swing angle)cos(thetaz) and Fz be Fcos(thetaz) or there situation that just like in the 2D system they can change??

@malwina8665 3 ай бұрын

I think that in the 2D the Fx coordinate is always cos as in the unit circle, and on the plane it’s Fx= Fcos(theta)
