The uniform links AB and BC each weigh 2 lb and the cylinder weighs 20 lb. Determine the horizontal force P required to hold the mechanism in the position when θ = 45°. The spring has an unstretched length of 6 in.
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 θ = 64°, 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.
The homogeneous cylinder of weight W = 100N rests in a frictionless right-angled corner. Determinethe contact forces NA and NB if θ = 30°.
