Homework Statement
Determine the angular velocity of the gear at the instant shown. Set v = 9ft/s and vc = 6ft/s. Assume counterclockwise is positive.
Homework Equations
v = w x rIC
The Attempt at a Solution
I tried solving this many times using va = v0 + (ω x ra0 ) and vb=v0 + (ω x rb0 ) but kept getting the wrong answer.
Then I ended up solving for the instantaneous center using similar triangles and used v = ωxrIC.
How do I know when to use an instantaneous center in my problem solving?
