The uniform slender bar AB has a mass of 0.8 kg and is driven by crank OA and constrained by link CB of negligible mass. If OA has an angular acceleration α0 = 4 red/s2 and an angular velocity ω0 = 2 red/s when both OA and CB are normal to AB, calculate the force in CB for this instant. (Suggestion: Consider the use of Eq. 6/3 with A as a moment center.)
