The wheel D rotates without slipping over a flat surface. The XY frame shown is inertial whereas the xy frame is attached to D and rotates with it at a constant angular velocity ωD. Collar C slides along the bar AB with a velocity υC relative to the xy frame. Suppose that ℓ, θ, and R are given and that we want to determine the inertial acceleration of C when the xy frame is parallel to the XY frame as shown. Would the expression of the inertial acceleration of the collar in the two frames be different or the same?
