A shaft 1.5 m long and diameter 10 mm has one end rigidly fixed to a frame support and the
other carries a rotor of inertia 0.045 kgm². If the period of free vibration of the system is 1.5
second,
i) Determine the modulus of rigidity of the material of shaft.

ii) If the amplitude of the oscillation is 10°, determine the maximum values of the velocity
and acceleration.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.
