The nests built by the mallee fowl of australia can have masses as large as 3.4 × 105 kg. suppose a nest with this mass is being lifted by a crane. the boom of the crane makes an angle of 45.0° with the ground. if the axis of rotation is the lower end of the boom, the torque produced by the nest has a magnitude of 3.75 × 107 n•m. treat the boom’s mass as negligible, and calculate the length of the boom.
