You are given the task to evaluate the following two machines. The requirement of the machines is to be in equilibrium with the minimum couple applied at A. Calculate the couple at A and reaction forces at A and B for both machines and make a recommendation on which machine should be produced. Justify your recommendation including how the mechanisms would compare in different positions as the angle at B changes. Machine Option 1 D C MA 250 lb-in. 15 in. 25 A B Machine Option 2 C D 15 in.- MA 250 lb.in. 15 in. 25 B A 15 in.- Describe how to calculate the reaction forces at A and B, the contact forces between components, and the couple at A for both machines. You should make a recommendation for the best machine option. Support your recommendation for the best mechanism including for different angles at B. Note: The blue-collar slides frictionlessly on the inside rod, BCD for Option 1 and ADC for Option 2.
