The yacht is anchored with a chain that has a total length of 40 m and a mass per unit length of and the tension in the chain at A is 7 kN. Determine the length of chain which is lying at the bottom of the sea. What is the distance d? Assume that buoyancy effects of the water on the chain are negligible. Hint: Establish the origin of the coordinate system at B as shown in order to find the chain length BA.
