Hi guys, My first time here. Looks like a nice forum with friendly members. I have a question. I'm kinda confused by this (and I know it's a shame since I'm on my third year University, almost making my degree). What I remember from my kinematics/dynamics classes this (or similar) equation always yielded the result in rad/s but now I'm stuck here. I can't justify it using SI units. What I get as output is 1/s which as much as I know is the Hz. Meaning 1 revolution per second and not 1 radian per second. If anyone could chime in and clarify this for me would be nice. Thank you in advance. P.S. My first time here. I didn't know how to insert math equations so I inserted a picture. If this is somehow against the site rules or in the wrong place feel free to remove it or tell me and I'll do it myself.
