The mechanism shown is one of two identical mechanisms attached to the two sides of a 180-lb uniform rectangular door. Edge ABC
of the door is guided by wheels of negligible mass that roll in horizontal and vertical tracks. A spring of constant k is attached to wheel
Bin such a way that its tension is zero when 0 = 30°. Knowing that the door is released from rest in the position 0 = 45° and reaches
the vertical position with an angular velocity of 0.6 rad/s, determine the spring constant k.
