To carry out dynamic force analysis of the four-bar mechanism shown in the figure. It is required to find the inertial radius of the links. Where 2 = 20rad /s (cw), a2 = 160 rad/s2 (cw) OA= 250mm, OG2= 110mm, AB=300mm, AG3=150mm, BC=300mm, CG4=140mm, OC=550mm, ZAOC = 60 The masses & mass moment of inertia of the various members are: Link MMI (IG, Kgm2) 2 WN 3 4 Mass, m 20.7kg 9.66kg 23.47kg Fit 00 3 F31 G3 VA 3 0.01872 0.01105 0.0277 1 (a) Scale: 1 cm = 10 cms F ABA 83 Y ABA AB Acceleration polygon Scale 1 cm = 20 m/sec Note: The listed scales are not perfectly correct, Consider the following values to find out the correct scale of acceleration polygon. V = 25020; 5m/s, VR 4 m/s, VRA = 4.75 m/s a = 25020; 100m/s, a = 250160; 40m/s
