2. The bar shown weighs 20 lb and is pivoted about a point C that is 1 ft from end B. The other end is pressed against a vertical
spring until the spring is compressed 2 in for the position shown. The rod is released from this position, and then comes to a
vertical position.
For a spring constant between 800 and 2000 lb/in, plot the angular velocity of the rod at the vertical position vs the spring
а.
constant. Use increments of 100 lb/in.
b. When the rod passes through 30 degrees above the horizontal, find the tangential component of the reaction at O.
