A uniform straight bar 2.00 m long and weighing 450 N is supported by two cables at its ends to the roof of a house. Cable 1 on the left end can withstand a maximum tension of 600 N without breaking, while Cable 2 on the right end can withstand a maximum tension of 500 N. You want to put additional weight on that bar. Calculate: (a) What is the maximum weight you can place on the bar without breaking any of the cables? (b) Where should you place this weight on the bar?
