    Graduate Need help drawing phase portraits for coupled systems of ODEs

    Okay, I know that this is probably a simple question but I've always been good at doing the complicated things and bad at doing the easy things :D Here's what I've got: Find the general solution for the system of coupled ODEs. Determine kind and stability of the critical point. Sketch phase...

    Circular Motion and Tension in a string

    Lets pretend I'm stupid (which I am) and that I don't know anything about dynamics (which I currently don't), can you explain more clearly what you mean? :D Thanks

    Flyball governor and force on slider

    I'm not sure how to split the force and recombine it. Do you mind stepping me through it? Thanks

    Circular Motion, a swinging ball and tension in string

    http://www.mech.uq.edu.au/courses/mech2210/yat/q/swinging_ball.jpg The mass of the ball is m, as given below in kg. It is released from rest. What is the tension in the string (in N) when the ball has fallen through 45o as shown. m[kg] = 3.335 I've used the formulae: v = sqrt[2gL(sin...

    Flyball governor and force on slider

    http://www.mech.uq.edu.au/courses/mech2210/yat/q/governor.jpg A flyball governor is a device used to regulate the speed of steam turbines in steam power plants. The rotation of the shaft causes the two balls move outward. As the balls move out, they pull on the bearing A. The position of the...

    Circular Motion and Tension in a string

    Okay, I have given this a go but its been 2 years since I've done any dynamics so I think I've done something stupid... A ball is attached horizontally by a string of length L to a central point C. The mass, m, of the ball is 4.775kg. It is released from rest and allowed to swing downwards...
