In this question, you will design a circuit that will detect if a given digit (0,1,2,39) is in your student number or not. For example if your student number is 16050511028 and you are given a digit 9, your output should be 0.
If you are given a digit 6, your output should be 1. Design this circuit using only 1-to-4 demultiplexers and OR
gates. You can use logic 0 and logic l as well. You need to design the most simplified circuit with these
components.

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
