The Sin long crank i.e. link 2 shown weighs 2 lb. Its centre of Gravity (CG) is at 3in and 30 from the line of centers. Its mass moment of inertia about its CG is 0.05 lb-in-s. Its acceleration is defined in its Local nonrotating coordinate system (LNCS) x, y. Its kinematic data are shown below. The coupler i.e. link 3 is 15 in long and weighs 4 lb. Its CG is at 9 in and 45 from the line of centers. Its mass moment of inertia about its CG is 0.10 lb-in-s. Its acceleration is defined in its LNCS, x, y. Its kinematic data are shown below. The sliding joint on link 3 has a velocity of 96.95 in/s in the +Y direction. There is an external force of 50 lb applied at point P which is located at 2.7 in and 201 from x-axis of link 3 Local Coordinate system. The coefficient of friction is 0.2. i. ii. iii. 0 deg 60 03 deg 99.59 00 rad/sec 30 @3 rad/sec -8.78 2 CG 3" 2 30 rad/sec -10 3 rad/sec -136.16 B 15" aG in/sec 2700.17 @ 89.4 aG3 in/sec 3453.35 @ 254.4 Draw a Free Body Diagram of each moving link of the mechanism.
