(35 pts total) A four bar linkage is going to be used to press fit a bearing into a hole in the green part on an assembly line. The tool (shown as the orange block) that will push the bearing into the hole is located at a distance rout = 40 cm from 04 along link four. Use the linkage notation shown in the schematic for this problem. B Fout B Fin A A e LNCS W2 04 Tout Tin a2 W 02 04 X GCS 02 04 The link lengths are rı = 30 cm, r2 = 40 cm, r3 = 25 cm, r4 = 50 cm. At the instant shown 02 = 55°, and the input link is moving with angular velocity of W2 = -0.2 rad/s and angular acceleration az = 0.1 rad/s2. A. (5 pts) Determine the angles 03 and 04 when 2 = 55° B. (5 pts) Find the angular velocities of the links w3 and 4. C. (5 pts) Find the angular accelerations of the links az and a 4. D. (5 pts) If a force of 125 N (Fin) is applied perpendicular to link 2 at a distance of rin = 25 cm along the link from O2 when the link is in the position described above, what is the mechanical advantage at the orange tool and the force (Fout) applied to the bearing?
