I have a few problems where I just need a push in the right direction:
(1) A tightly stretched "high wire" is 46.5 m long. It sags 3.49 m when a 59.7 kg tightrope walker stands at its center. What is the tension in the wire? I have no idea what to do on this problem...
(2)A 36.6 kg round table is supported by three legs placed equal distances apart on the edge. What minimum mass, placed on the table's edge, will cause the table to overturn? Neglect the mass of the legs. Wouldn't I need to know some other information like radius or something?
(3)A cube of side l = 120 cm rests on a rough floor. It is subjected to a steady horizontal pull, F, exerted a distance h = 83.0 cm above the floor. As F is increased, the block will either begin to slide, or begin to tip over. What is the maximum coefficient of static friction for which the block begins to slide rather than tip? Wouldn't I ned to know F to figure this out? Keep in mind my answer has to be a numerical value, not a formula.
Any tips on any problem would be greatly appreciated. Thank you so much for helping...
