11.64 . A uniform metal bar that is 8.00 m long and has mass 30.0 kg is attached at one end to the side of a building by a fric- tionless hinge. The bar is held at an angle of 64.0° above the horizontal by a thin, light cable that runs from the end of the bar opposite the hinge to a point on the wall that is above the hinge. The cable makes an angle of 37.0° with the bar. Your mass is 65.0 kg. You grab the bar near the hinge and hang beneath it, with your hands close together and your feet off the ground. To impress your friends, you intend to shift your hands slowly toward the top end of the bar. (a) If the cable breaks when its tension exceeds 455 N, how far from the upper end of the bar are you when the cable breaks? (b) Just before the cable breaks, what are the mag- nitude and direction of the resultant force that the hinge exerts on the bar?
