The primary difference between integrated/concurrent engineering development and functional/sequential development is: Integrated development spends more money up front to order to save money in later stages. Sequential development is more thorough in addressing development steps. In sequential development, multiple functions co-manage design and testing. Integrated development usually leads to higher sustaining and warranty costs.

Practice Problem: True Stress and Strain A cylindrical specimen of a metal alloy 49.9 mm long and 9.72 mm in diameter is stressed in tension. A true stress of 376 MPa causes the specimen to plastically elongate to a length of 53.5 mm. If it is known that the strain-hardening exponent for this alloy is 0.1, calculate the true stress (in MPa) necessary to plastically elongate a specimen of this same material from a length of 49.9 mm to a length of 58.2 mm.

D * 4.80 It is required to use a peak rectifier to design a dc power supply that provides an average dc output voltage of 12 V on which a maximum of ±1-V ripple is allowed. The rectifier feeds a load of 200. The rectifier is fed from the line voltage (120 V rms, 60 Hz) through a transformer. The diodes available have 0.7-V drop when conducting. If the designer opts for the half-wave circuit: (a) Specify the rms voltage that must appear across the transformer secondary. (b) Find the required value of the filter capacitor. (c) Find the maximum reverse voltage that will appear across the diode, and specify the PIV rating of the diode. (d) Calculate the average current through the diode during conduction. (e) Calculate the peak diode current.
