How Can People Prepare for Certification? Certification training options are available to suit every learning style. Self-study programs help professionals prepare for certification at their own pace and supplement other training methods. Online training classes, which are available on the Internet and on many company intranets, allow students to set their own pace in an interactive environment. Instructor-led training classes are available in a variety of forms, including seminars, boot camps, and academic-style classes. Web resources include the certification sponsor's Web site and individual Web sites. The certification sponsor's Web site can contain descriptions of certifications with FAQs and links to authorized training and testing centers. Detailed course objectives, training guides, sample test questions, chat rooms, and discussion groups often are included. Individuals also set up Web sites to offer their own views and tips on the testing process.

If the mass diffusivity of hydrogen is 9 X 10-7 m2/s, how much time is required to bring the density of dissolved hydrogen to a value of 1.2 kg/m3 at the center of the sheet?
It is subjected to concentrated loads of 20,000 lb at each quarter point and an axial tensile load of 50,000 lb. Calculate the maximum combined tensile and compressive stresses.
Let H/ z ) be the system function of a discrete-time prototype low-pass filter. Consider a new discrete-time low-pass filter whose system function H( z ) is obtained by replacing z in H/ z ) with ( z - a )/{1 -az ), where a is real.
Air is contained in a piston-cylinder assembly, initially at 40 psia and 600 R. The air expands in a polytropic process with n = k = 1.4 until the volume is doubled. Modelling the air as an ideal gas with constant specific heats,
find how long it takes for the center of the chicken to reach this temperature.
