Homework Help: physics

Posted by sand on Saturday, November 12, 2011 at 6:05pm.

A steel beam (with linear mass density of 6.88 kg/m) has a total length of 10.0m and is suspended by two cables such that the beam hangs horizontally. Cable A is attached 1.00 m from the left end of the beam and cable B is attached 3.00 m from the right end of the beam. A 75.0 kg man is standing on the beam a distance of 2.5 m from the left end and a 3.5 kg cat is sitting, with a wry smile, 1.00 m from the right end of the beam. Assuming the cables are massless, what is the tension in Cable A?_________N What is the tension in cable B? _________N Some time later, after the man has kicked the cat off of the beam, the man is standing at the right edge of the beam. Should he be worried about the stability of this situation? explain.___________________________________________
