In addition, the a vertical shaft which is rotating about the fixed Y ˙ raised at a crate of θ. In addition, the tube is attached to tube is attached to a onstant axis withis rotating aboutof ω .fixed observer is attached to the tube with the xyz axes also attached a constant rate the An Y axis with a constant rate of vertical shaft which to . An observer is origin at point O. ! = 4 rad / secthe tube with its attached to the tube with the xyz axes also attached to the tube with its origin at point O. Find: For the position shown, determine: You are asked • the angular velocity vector of the observer.= 5 feet and ! = to find the acceleration of particle P when R 36.87°. In doing so, answer the following questions. a) b) c) d) e) Find the • ngular velocity vector of vector of the. observer. a the angular acceleration the observer Find the • ngular acceleration vectorseen byobserver. a the velocity of point P as of the the observer. What is the velocity of point P as seenas seen observer? • the acceleration of point P by the by the observer. What is the acceleration of point P as seen by the observer? • the acceleration of point P using the above results. Using the results from a)-d) above, find the acceleration of point P. Y x P y R ! O X " ˙ ˙ Use the following parameters in your analysis: R = 5f t, θ = 36.87◦ , R = 6f t/sec, θ = 3rad/sec and ω = 4rad/sec.
