An experiment was conducted to test the effects of a high-protein diet on the ability of chickens to lay eggs that have a high-protein content. ten chickens were obtained from three chicken-breeding farms (all were hens), and their diet consisted of a mixture of fish, cheese, and soybeans. eggs produced from this group of chickens were found to have a slightly higher protein content than eggs purchased at a local grocery store. from this, the investigator concluded that the diet fed to the chickens was responsible for the protein increase in the eggs. how would you analyze these results, using critical thinking?

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
