One metric for measuring requirements specification is “Correctness”. The correctness factor Cr can be calculated by Cr=R_c/(R_c+R_nv ), where R_c is the number of correct requirements and R_nv is the number of still not valid requirements. The metric Cr is used to measure percentage of requirements in the SRS that have been validated. What is the Cr of your workgroup project specification. Justify your answer.

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Apressure vessel with an r/t 20 cannot be treated as thin walled vessel. a)-trune b)- false

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
