For the mechanism shown in Figure P3.39,

(a) draw the velocity polygon (employ scale: 
1  cm  = 10 cm/sec)

(b) draw the acceleration polygon (employ
scale: 1 cm = 100 cm/sec2)

(c) specify

(i) the acceleration of point B6

(ii) the angular accelerations of links 3 and 6

(d) if the angular velocity of link 2 is changed to a
constant rate of 80 rpm CCW, specify the new angular acceleration for link 6
