A weight W hangs from two steel cables ofequal length attached to each other as shown.The combined length of both cables is 26 m.The cross section of upper cable is 20 mm²whereas the cross section of the lower cable is80 mm². The Young's modulus of both cables is200,000 N/mm². If the total extension of the combined cable is 3mm, determine that value of the weight W in-newtons. Round off your answer to the nearest-Newton.
