Problem #6 The figure shows top and side views of a control knob A that slides smoothly in a slot cut in a panel and is attached to a spring underneath the panel. Determine the force in the spring and the distance s, for which the knob will be in equilibrium when a 0.5-lb force is applied. The unstretched length of the spring is 4 in., and the weight of the knob is negligible. 4 in B Top view A 0.5 lb A 0.5 lb k=5 lb/in. Side view 3
