[QUOTE="Nikstykal, post: 5501721, member: 584563"] [h2]Homework Statement [/h2] Determine the angular velocity of the gear at the instant shown. Set v = 9ft/s and vc = 6ft/s. Assume counterclockwise is positive. [ATTACH=full]188626[/ATTACH] [h2]Homework Equations[/h2] v = w x r[SUB]IC[/SUB] [h2]The Attempt at a Solution[/h2] I tried solving this many times using va = v0 + (ω x r[SUB]a0[/SUB] ) and v[SUB]b[/SUB]=v0 + (ω x r[SUB]b0[/SUB] ) but kept getting the wrong answer. Then I ended up solving for the instantaneous center using similar triangles and used v = ωxr[SUB]IC[/SUB]. How do I know when to use an instantaneous center in my problem solving? [/QUOTE]
