Q1
convert the bearings to azimuths from north and compute
theangle . smaller then 180 degree. between successive
bearings.
n66 degree 17' 36"e, s44 dgree 22'34"e, s8 degree 23' 42"w, and
n57 degree 08' 55"w.

q2
compute theazimuth from north of lin cd . ( azimuths of ab
arealso from north.)
bearing ab= s59 degree 48' 23"w; angle to the right
abc = 205 degree 56' 11" , bcd= 195 degree 23' 08".

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
