So the bar is 1.7 meters long and its mass is 6 kilograms. The auto repair sign also has a mass of 15.50 kilograms. The cable that is connected to the bar is 1.35 meters long and it is at a 35 degree angle The homework problem wants to know what is the tension in the cable and what the instantaneous angular acceleration of the sign/bar system would be if the cable snapped.
