A weight (with a mass of 90 kg) is suspended from a point near the right-hand end of a uniform boom with a mass of 71 kg . To support the uniform boom a cable runs from this same point to a wall (the left-hand vertical coordinate in the figure) and by a pivot on the same wall at an elevation of 4.5 m. Calculate the tension T in the cable. The acceleration of gravity is 9.8 m/s2 . Answer in N. Please help!
