Rocky Top hardware specializes in manufacturing steel bars. The process starts with raw material (carbon steel wire), and then progresses sequentially through five steps using machines A to E, respectively (see table below). This is the only use that the five machines are put to. The hourly throughput rates (in Ibs/hour) for each machine are given below. Raw Step 1 Step 2 Step 3 Step 4 Step 5 - Market > Demand A Materials B D E 95 lbs/hr 70 lbs/hr 40 lbs/hr 50 lbs/hr 110 Ibs/hr 1. What is the maximum system output of steel product per hour? 110 lbs 2. If machine C in Step 3 works at full capacity, what is the maximum number of steel bars waiting to be processed by machine D in Step 4 at the end of an 8-hour day (both machine C and D work for 8 hours)? Select] 3. Which of the following machines are bottlenecks, if market demand is 90 lbs/hour? Select] 4. If market demand is 90 lbs/hour, the following resource is the constraint: 4. If market demand is 90 lbs/hour, the following resource is the constraint: Select) 5. By how much would the hourly system output be improved if the capacity of machine C was increased to 80 lbs/hour?
