The pressure in an automobile tire depends on the temperature of the air in the tire. when the air temperature is 25°c, the pressure gage reads 210 kpa. if the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire rises to 44°c. also, determine the amount of air that must be bled off to restore pressure to its original value at this temperature. assume the atmospheric pressure to be 100 kpa.

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
