2 pulley system with three masses. Find the two outside masses.

[QUOTE="Simon Bridge, post: 4547788, member: 367532"] Lets see if I have this right: A string goes from m1, over a pulley, to m3; and another string goes from m3, over another pulley, to m2. The whole situation is static - no motion. Then sum the forces to zero. m1 and m2 are hanging vertically - held by tensions T1 and T2 respectively. Which gives you T1 and T2 right away - in terms of m1 and m2. m3 is hanging from two angled strings, tensions T1 and T2 again - since the tension has to be the same over each pulley. I don't know how you get 3 tensions. T1 acts upwards at angle A to the vertical and T2 acts unpwards at angle B to the vertical. The remaining force is the weight - vertically downwards. The horizontal and vertical components must sum to zero. You need to use trigonometry to get the components of T1 and T2. [/QUOTE]
