A weight (with a mass of 71 kg) is suspended from a point near the right-hand end of a uniform boom with a mass of 51 kg . To support the uniform boom a cable runs from this same

point to a wall (the left-hand vertical coordinate y=7 x=6) and by a pivot on the same wall at an elevation of 3 m.

Calculate the tension T in the cable. The
acceleration of gravity is 9.8 m/s2 .
