stretching occurs at 2960 cm−1 . By comparison‚ methylene groups show asymmetric stretching at 2930 cm−1 and symmetric stretching at 2850 cm−1 . C–H bending gives rise to bands in the region below 1500 cm−1 . Methyl groups produce two bending bands‚ i.e. a symmetrical band at 1380 cm−1 and an asymmetrical band at 1475 cm−1 . Methylene groups give rise to four bending vibrations: scissoring (1465 cm−1 )‚ rocking (720 cm−1 )‚ wagging (1305 cm−1 ) and twisting (1300 cm−1 ). The intensity of the methylene CH2

heater core tubes includes three parts: the pressing machine‚ the bending machine‚ and the washing machine. The pressing machine takes seven seconds per tube; the bending machine takes 13 seconds per tube‚ and the washing machine takes 0.06 seconds per tube (60 seconds per 1000 tubes). Each of these processes runs simultaneously‚ so the theoretical capacity is constrained by the process that takes the longest period per tube: the bending machine. Under the current policy‚ Hilcrest Auto is operating two

(2) inner bending‚ and (3) outer bending. The cutting process can produce at a rate of 150 pieces per minute; inner bending‚ 140 pieces per minute and outer bending‚ 110 pieces per minute a. Determine the hourly capacity of each process stage and the number of machines needed to meet an output rate of 20‚000 units per hour. 1. Cutting: 150(min) (60 min=9‚000/hour) = 20‚000/9‚000=2.22 machines needed 2. Inner Bending:140/min (60)= 8400/hour 20‚000/8400=2.38 machines needed 3. Outer Bending:110min(60)=6600/hour
