Question $2$

The mechanism shown below is in static equilibrium under the horizontally applied external force $P=20$ N at the given instant.

a$)$ Draw the free body diagrams of all the links, showing all unknown forces.

b$)$ Write the equilibrium equations for each link $($Neglect gravitational, frictional and inertial effects.$)$

c$)$ For the given parameters and applied external force $P=20N,$ determine the torque $T_2.$

$|AB|=45mm,|BC|=67mm,|BE|=60mm$

$|CD|=18mm,|DO|=42mm,|EO|=23mm$

${}_{12}=235,{}_{13}=150,{}_{14}=215$
