Q13:- A certain machine requires a torque of (5000 + 500 sin 0) N.m to drive it, where 0 is the angle of rotation of shaft measured from certain datum. The machine is directly coupled to an engine which produces a torque of (5000 +cos 20) N.m. The flywheel and other rotating parts attached to the engine has mass of 500 kg and a radius of gyration of 0.4 m. If the mean speed is 150 rpm, find (a) the fluctuation of energy, (b) the total percentage of fluctuation of speed and (c) the maximum and minimum angular acceleration of the flywheel and the corresponding shaft positions.

hints: The ﬂask will be filled with water (at a constant rate of 500 gallons per minute). It will take me exactly 10 minutes to escape from the chains. The diameter of the tank at 1 foot intervals. I am 5 feet 9 inches tall, and I'm pretty skinny so that you can ignore both my volume and the volume of the stool in your analysis. A gallon is equal to 0.13368 cubic feet. You can think of the volume and the height of the water as functions of time. You can easily find an expression for V (t), and then use your expression for volume in terms of height to solve for h(t). after 10 minutes amount of water in the tank=66.84 ft3 t=69.3 minutes h(t)=e66.84t/100pi -1 h(10)=e66.84(10)/100pi -1=7.39 ft Height of stool=1.64 ft Height of water in the tank=7.39 ft Questions: show work How fast is the water rising?

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
