**Task A:** The design of a robotic system calls for the two-rod mechanism shown below. Rods AC and BD connected by a slider block D as shown. Neglecting the effect of friction, consider how you would determine the couple MA required to hold the rods in equilibrium for values of θ from 0 to 120° using 10° increments. For the same values of θ, how would you determine the magnitude of the force F exerted by rod AC on the slider block?

**Task B:** Consider the possibility that someone will pull AC down and add a perpendicular force to your system. Does this affect the stability of the system? How can we know at what point the added force will cause the system to fail?
