(b) If this amount of mass is hanging off the boom, where is the center of gravity of the entire system relative to C.G. (base)? Assume the mass m is located 1.50 m vertically higher than the C.G. (boom). (c) What is the corresponding tension in the cable assuming the cable makes an angle of 46.5o relative to the horizontal? (d) What is the strain in the boom’s pin (support)?
