Q6: The 7-kg collar A slides with negligible friction on the fixed vertical shaft. When the collar is released from rest at the bottom position shown, it moves up the shaft under the action of the constant force F 200 N applied to the cable. Calculate the stiffness k which the spring must have if its maximum compression is to be limited to 75 mm. The position of the small pulley at B is fixed.

Q6: The 7-kg collar A slides with negligible friction
on the fixed vertical shaft. When the collar is
released from rest at the bottom position shown, it
moves up the shaft under the action of the constant
force F = 200 N applied to the cable. Calculate the
stiffness k which the spring must have if its
maximum compression is to be limited to 75 mm.
The position of the small pulley at B is fixed.
