Homework H$\mathrm{.}2.$F

Given: The circular disk shown rolls without slipping on a straight horizontal surface. Bar AB is

pinned to point $A$ on the disk, with end $B$ constrained to move along a smooth horizontal surface

with a constant speed $v_B.$ At the position shown, A is directly to the right of the center O of the disk.

Find: For this position:

$($a$)$ Determine the angular velocities of link AB and of the disk. Write your answers as vectors.

Use the following parameters in your analysis: $R=6in,L=10in$ and $v_B=100i\frac{n}{s}.$

use

vA $=$ vC $+\backslash$omega disk x rA$/$C $=\backslash$omega disk x rA$/$C

vA $=$ vB $+\backslash$omega AB x rA$/$B $=$ vB $*$ i $+\backslash$omega AB x rA$/$B
