A sign is supported by a cable and a horizontal beam.The beam has a length 1.4 m and a uniform mass of12 kg.a) If the cable is attached to the beam at a distance of 1.0 m from the hinge, what is the tension in the cable? (b) If the cable breaks, what is the net torque on the beam the instant thereafter?
