[SOLVED] Tension in Strings HELP thanks!--very simple.
A 16 kg object hangs in equilibrium from a string with a total length of L=5m and a linear mass density of u= 0.0010 kg/m. The string is wrapped around two light, frictionless pulleys that are separated by a distance of d=2.0m.
A) Determine the tension in the string.
B) At what frequency must the string between the pulleys vibrate in order to form the standing-wave pattern shown in Figure b)?
Picture is attached!
If there was an axis at the bottom of the inverted triangle and the angles were measured from the axis to the strings;
I have also tried using;
v = Square root of (tension/u), but I don't have v,
So i tried to find v using f = v/ wavelength, but i don't have frequency.
I have tried so many things and I can't seem to get a start. Any hints?
