Find the frequency ratio
at which the amplitude of a single-degree-of-freedom damped system attains the maximum value. Also find the value of the maximum amplitude.
Methane is completely burned with 20% excess air, with 30% of the carbon going to CO. What is the partial pressure of the CO in the stack gas if the barometer reads 740 mm Hg, the temperature of the stack gas is 300°F.
Assume the racing car travels at a speed of 270 km h on a track where normal atmospheric pressure and a temperature of 30°C prevail.
A 45 kg machine is mounted on a spring of stiffness 8x10^5 N/m. When the machine is set to vibration by a 32 Hz excitation, the machine's amplitude is measured as 1.5mm. What is the amplitude of the excitation provided to the machine? Ignore damping ..
