Homework Statement
"Knowing that crank AB has a constant angular velocity of 160rpm counterclockwise, determine and plot, for values of [tex]\theta [/tex] from 0 to 360 degrees, (a) the angular velocity and angular acceleration of rod BD, (b) the velocity and acceleration of collar D.

Homework Equations
I don't know! :(
The Attempt at a Solution
[tex]\lamda =160rpm=160(\frac{2\pi}{60})rad/s[/tex]
Unfortunately this is as far as I've been able to get. The reason is because I'm not sure as how to derive an equation that would allow me to plug in a value from 0 to 360 for theta and it give me beta (angle of bar BD from the horizontal). If I can just get past that point I can figure the rest out. With any other problem there is a fixed position in which I can just use the triangle method to figure it out but i can't really do that here.
