1. The problem statement, all variables and given/known data 1) The horizontal slot guide C moves downward at a constant velocity of 4.00 in/sec. Crank OP (radius rOP) is pinned at O and point P slides freely in horizontal slot guide. At the instant shown determine: a) θ’ (The angular velocity of OP) b) θ’’ (The angular acceleration of OP) θ = 50.0º rOP = 8.00 in Image 2) Collar C (weight w) is free to slide on the vertical steel rod (diameter d; length L). The collar is released from rest at a height of h above stopper A at the end of the rod. Determine the maximum force experienced by the rod. w = 5.00 lbs d = 1/8 in L = 2.00 ft h = 18.0 in ESTEEL = 29000 ksi; Image 3. The attempt at a solution I don't even know where to start. My professor didn't put up the equation sheet and I didn't understand it when he did it in lecture earlier today. If someone could patiently help me through this I would appreciate it.
