Homework Statement
http://imgur.com/yVOXkAT
The two disks each have a mass of 18kg and are attached at their centers by an elastic cord that has a stiffness of k = 1.6kN/m . Determine the stretch of the cord when the system is in equilibrium and the angle θ of the cord. (Figure 1)
Homework Equations
F_x=0
F_y=0
The Attempt at a Solution
So far I've determined that the forces in the X-direction equals zero so cos(theta)lengthk=294.34(horizontal force of the left disk)
and in the y-direction,
sin(theta)lengthk=176.58(the y force of the right disk)
I believe this to be all I need, but I'm having trouble solving two equations with a sin and cos, and even then I'm not entirely sure if my calculations are correct. Any help is appreciated.
