Why, do you suppose, an architect must have a minimum of a bachelor's degree, be licensed in every state, and often encouraged to pursue advanced degrees or additional professional training? Select all that apply.
Architects must maintain a level of professional care and attention to detail that assures their designs meet with accepted standards.
Architects need not have a bachelor's degree; many become licensed through apprentice programs.
Technology continues to influence building design by making it possible to produce new, stronger building materials and architects must
be aware of the use and limitations of new materials
The licensing provisions for architects typically require a minimum of a bachelor's degree in design and related coursework to assure all
graduates have approximately equal training and knowledge

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?
