A6.3 – A point Q (not shown) moves all the way from A to B along link 3 (shown below) while link 2 rotates from 02 = 45° to 0'2 = 225°. Draw and report the absolute displacement vector of Q. (Hint 1: Try drawing the vectors for the joints and point Q in the initial and final position overlayed with each other and attempt the arithmetic for the resulting vectors. Hint 2: Working in ijk “hat" notation may help with the arithmetic.)
