Part A.)The slender bar AB rests on a smooth surface at B and is attached to a collar A that slides freely on the smooth vertical rod. The bar has a uniform cross section and a mass of 20 kg; the collar has negligible mass. The bar is initially at rest when theta is zero degrees when it is disturbed and rotates in a vertical plane under the action of gravity. Determine the angular acceleration (using force-acceleration methods) of the bar and the reactions at A and B when theta is 60 degrees.

Part B.) The bar is initially at rest with theta=zero degrees when it is released and rotates in a vertical plane under the action of gravity as in part A. Plot the reaction at A for a range of theta in the domain 0 less than or equal to theta less than or equal to 90 degrees. On the same graph, compare the results for a mass of 10kg, 20kg and 30kg.

On a separate graph, plot the reactions at B for the same domain of theta and compare the results for masses of 10, 20 and 30kg.
