    Graduate Solving System of Non-Linear Diff. Equations

    T = dL/dt? I don't get that part. L is the length of the cable joining the two masses. T is the tension in the cable.

    Graduate Solving System of Non-Linear Diff. Equations

    Oh and I may add that on my drawing, the angle \theta looks like its initial value is NOT zero because I put a certain angle there. I deliberately put an angle to be able to build up my equations.

    Graduate Solving System of Non-Linear Diff. Equations

    Regarding the hand-writing, if it's not clear on paper, it won't be clear in my mind! Now. The problem. You're right, it's a pendulum "m" free to rotate about point O located on Mass "M". The mass "M" is not quite "free" to move since there is some friction acting on it (Friction = -bx')...

    Graduate Solving System of Non-Linear Diff. Equations

    I first thought of solving the second equation but since my initial conditions are all zero and there is no input function in my second equation, theta is simply going to end up being zero. I attached picture of the actual physical problem I need to solve.

    Graduate Solving System of Non-Linear Diff. Equations

    Hi, I'm new to this forum. It looks like an amazing source of information and people here seem to be helpful and knowledgeable. Briefly, I'm an undergrad student currently studying Mechanical Engineering at Concordia University, Montreal, Canada. The first equation seems a bit tricky...
