look at "oppgave 5".
In the problem, you have a massless string with 4 uniform masses attached symmetrically, and you are supposed to show that the implicit equation for x (and x = cos(alpha)) is correct. Each of the masses are L/5 apart and the distance between the two ends of the string is D.
The Attempt at a Solution
I should be getting 5 equations for the 5 unkowns, but I am only getting 4 (the last 4 equations written on the paper)..
