The clamp seen at point A in the figure can slide without friction along the vertical bar and is attached to a spring as shown. The elasticity constant of the spring is k =660 N/m. The length of the unstretched spring is lo = 300 mm. We know that the system is in equilibrium when h =400 mm. Determines the weight of the clamp. round your result to integers.
