In the wind tunnel for the air temperature difference of 100o C between air and the scaled model the energy transfer due to the heat was measured to be about 400W. At the reentry condition with 1500o C Temperature how much is the energy transfer due to the heat to the module? For a consistence modeling find the ! " scaling ration.

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
