3.34 Design a logic circuit that has five input variables and one output variable. Four of the input variables represent BCD digits, and the fifth is a control line. While the control line is at logic 0, the output should be logic 1 only if the BCD digit is greater than or equal to 5. While the control line is high, the output should be logic 1 only if the BCD digit is less than or equal to 5.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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
