A machine makes two components; call them types A and B. It takes 250 seconds to switch production between the component types. During that time, no production occurs. When in production, each unit of A or B requires 0.5 second to be completed. The two components, A and B, are combined in an assembly process to make a final product; call it C. The assembly step can combine the two components into 1 unit every 2 seconds, or 30 units per minute. Assume there is ample demand. Suppose the machine rotates between one batch of 1,000 units of A and 1,000 units of B. What is the average inventory of B components? answer:______units

2. You wish to lift a 15,000 lb stone by a vertical distance of 25 ft. Unfortunately, you can only generate a maximum pushing force of 2,500 lb. a. Sketch the diagram representing the problem b. What is the amount of work you must input in order to move the stone? c. What is the actual mechanical advantage (AMA) required by a machine to complete the work above? d. You build a ramp to create the ideal mechanical advantage. What is the length of the ramp in feet?
