Question $1$: AO rotates as shown below at constant speed. When AO forms a $20$ degree angle with the horizontal, determine the velocity of roller B$.$ Ignore the mass of the members.

Complete the following:

C$)$ Hand draw vector diagram for velocities using relative velocity of $B$ relative to A $.$ Calculate the velocity at B using this method also.

SOLVE THIS USING EITHER VECTOR OR TRIANGLE METHOD.
