1. The problem statement, all variables and given/known data A weight with mass m is strung up by two strings which are attached in A and B. The mass m is considered a point. Calculate the tension i in string A and in string B. Figure is here http://tinypic.com/r/1y1jrr/6 The mass m is 11,1kg Distance a is 3,2m Distance b is 3,4m Distance c is 2,6 m Distance d is 3,7m (I'm translating directly from Danish, so I might not have gotten all the terms into correct English...) 3. The attempt at a solution The first thing I did was to calculate the force G for the weight using G= mg = 11,1*9,81 = 1089N. I then tried to find the angles between the strings and the imaginary x-axis by using the measurements provided. The angle between string A and the x-axis(angle v1): invers tan 3,2/2,6≈51° The angle between string A and the x-axis(angle v2): invers tan 6,6/3,7≈61° I then set up two equations, one for the horisontal force and one for the vertical force: Horisontally: A*cosv1-B*cosv2=0 Vertically: A*sinv1+B*sinv2=108,9 And this is where I get stuck... I don't even know if I'm going about this the right way so I'd appreciate it if someone could have a look at it and point me in the right direction.
