(first order ordinary differential equation) a solution containing 90% by volume of alcohol (in water) runs at liter per min into a 100-liter tank of pure water where it is continually mixed. the mixture is withdrawn at the rate of 1 liter per min. the alcohol volume in the container, nis given as d, = 10-100, 200 ls] 0 we would like to predict the alcohol volume in the tank, nas a function time. use m-1 s. solve this problem using matlab/octave script

(a) what is the alcohol volume in the container using analytic approach for 0 s is 200 [s]?
(b) what is the alcohol volume in the container n), using fdm for 0 t 200 [s]?
(c) what is the alcohol volume in the container n(t), using matlab/octave built-in function, "ode45" for 0 s 200 [s]?
(d) plot the results of parts (a) to (c) in the same figure to confirm your solutions are reasonable.
(e) what is the alcohol volume in the container n(t) at the steady-state condition, i. e., what is the alcohol volume in the container atofrom the solutions from parts (a) to (c)?

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?
