The 23-lb collar A is released from rest in the position shown and slides with negligible friction up the fixed rod inclined 28° from the horizontal under the action of a constant force P = 39 lb applied to the cable. Calculate the required stiffness k of the spring so that its maximum deflection equals 8 in. The position of the small pulley at B is fixed.

Step 1
The forces acting on collar A are its weight (23 lb), the applied force P (39 lb), the spring force $F_s = kx$, and the normal force from the rod. Show more…

The 30 -lb collar $A$ is released from rest in the position shown and slides with negligible friction up the fixed rod inclined $30^{\circ}$ from the horizontal under the action of a constant force $P=50$ lb applied to the cable. Calculate the required stiffness $k$ of the spring so that its maximum deflection equals 6 in. The position of the small pulley at $B$ is fixed.
The 3 -lb collar is released from rest at $A$ and slides freely down the inclined rod. If the spring constant $k=4 \mathrm{lb} / \mathrm{ft}$ and the unstretched length of the spring is 50 in., determine the speed of the collar as it passes point $B$.
