Question
The torsional spring at B is undeformed when bars OB and BD are both in the vertical position and overlap. If a force F is required to
position the bars at a steady orientation 0 = 54°, determine the torsional spring stiffness kt. The slot at C is smooth, and the weight of
the bars is negligible. In this configuration, the pin at C is positioned at the midpoint of the slotted bar.
