Suppose we are given the following information about a signal x[n]: 1. x[ n] is use the fourier transform analysis equation (5.9) to calculate the fourier transforms of: (a) (~)11 - 1 u[n- 1] (b) (~)ln-iia real and even signal. 2. x[n] has period n = 10 and fourier coefficients ak. 3. a11 = 5. 9 4. yo 2: : jx[nji2 = 50.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

Journeyman training is usually related (clo2) a)-to specific tasks b)-to cost analysis of maintenance task c)-to control process to ensure quality d)-to installation of machinery

What are the two (02) benefits, which may result from a successful implementation of preventive maintenance (pm) program in an organization? (clo3)a)- lean manufacturing b)-overlapping responsibilities c)-the planner is not qualified d)-accurate contractor information e)-reduction in equipment redundancies f)-accurate stores information
