Question

A slotted link is rotating about fixed pivot O with a counterclockwise angular velocity of 3 rad/s, and a clockwise angular acceleration of 2 rad/s2. The movement of the link is causing a rod to slide along the curved channel, as shown. The radius of the channel as a function of θ is given by, R = 0.7θ (with R in meters and θ in radians). Determine the radial and circumferential velocity and acceleration components of the rod at θ = 45°

Hi Christine!

 

This sounds like a fascinating question, but, without the diagram it refers to, I cannot be much help, as I am not sure of the geometry.  Is there any way to let us see the diagram (through imgur or some other means)?
