Acolumn fixed at both ends is intially curved whose equation of curue is given by y = 0.5 sin πx/2 m. it is subjected to an axial eccentric load of 50 kn in compression at 1.5 cm eccentricity. determine the maximum stress induced if its cross-section is 6 cm x 8 cm. e=200gpa

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
