The design of arobotic system calls for ther two-rod mechanis shown. Rods AC and BD are connected by a lider block D as shown. Negelcting th eggect of friction, write a omputer porgram and use it to determine the the couple M_A required to hold the rods in equilibrium for values of theta to 120 degress using 10 degreee increments. For the same values of theta, determine the m,agnitude of the force F exerted by Rrod AC on the slider block.
