Develop a c++ class called time the class maintains a member variable: an integer value which maintains an hour value between 0 and 23. the class maintains a second member variable: an integer value which maintains a minute value between 0 and 59. develop the following member and friend functions for the time class: constructor (pass in the hour and minute values as parameters; if not in range for either, clamp it to either end) copy constructor = operator (copy assignment operator) < < operator (print the string value for the time) ++ operator (increment the time by one minus) -- operator (decrement the time by one minute) += operator with an integer value for the right hand side (add some number of minutes) -= operator with an integer value for the right hand side (subtract some number of minutes) test the time class as effectively as you can

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?
