A risk that has become reality in your project has led to a cost increase. You have already used the funds
reserved to handle this risk and have concluded that you need additional funds that the project does not
have. Who is the most likely person or group you need to ask for help?

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?

Measuring the distance between two trees, you measure that there are 75.5 steps between the two trees. give an estimate of the unit of measurement of one step in meters and give an estimate of what you think its uncertainty is. give the distance that separates the trees in meters as well as feet/inches and round to the correct amount of significant digits. what would you say are the uncertainties for the these two distances
