From 1925 through 1963, burma shave advertising signs appeared next to the highways all across the united states. there were always four of five signs in a row containing pieces of rhyme, followed by a final sign that read "burma shave." for example, one set of signs that has been preserved by the smithsonian institution reads as follows: shaving brushesyou will soon see'emon a shelfin some museumburma shave find a classic burma shave on the web. write, compile, and test a class that outputs five lines so that each displays one line of this burma shave slogan in turn.

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?
