Afirst order measurement system with a time constant of 0.2 seconds is used to measure a harmonically varying voltage. the peak-to-peak amplitude of the input signal is 8 volts at a frequency of 6 hz. calculate: (i)-mean-lo-peak amplitude of the output signal (ii)phase lag (in degrees) of the output signal (iii)time delay (lag) of the output signal.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise

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
