At-intersection without the north approach has the following design volumes: south approach: nbl 1 lane at 90 vphpl; nbr 1 lane at 115 vphpl east approach: wbt 1 lane at 292 vphpl; wbl 1 lane at 31 vphpl west approach: ebt 1 lane at 133 vphpl; ebr shared with through lane at 56 vphpl draw this intersection including its 3 approaches (with north pointing up), the lanes and the arrows for the permitted movements. write the nema numbers 1 to 8 next to these available arrows. write the design volumes next to the arrows.

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
