The homogeneous semicircular hoop rocks back and forth on the horizontal surface without slipping. Determine the natural circular frequency of oscillations for small amplitudes. Assume simple harmonic motion.
Calculate the force on a wall subjected to a two-phase jet that has the following parameters:
Air flows steadily from a tank, through a hose of diameter and exits to the atmosphere from a nozzle of diameter as shown below. The pressure in the tank remains constant at 3.0 kPa (gage) and the atmospheric conditions are standard temperature and p..
a central-receiver solar thermal powerplant uses 1000 heliostats that have 50 m2 of reflecting surface each. the steam
Label all chip numbers (but not pin numbers). Specify the =12,-12, and +5 power supply connections, resistor values, and capacitor values. Offset null potentiometers are not required.
Determine the stress matrix components and epsilon_zz for known epsilon_xx, epsilon_xy, epsilon_yy for a) plane stress and b) plane strain condition incorporating thermal strains.
determine the required diameter of the balloon if it is approximated to be a sphere. Also explain why the load is to be carried below the balloon. Note the specific weigh t of air at various temperatures is available in the Appendix E.
an equiangular strain gage rosette is mounted on a free and unloaded surface of a part made of steel. when loaded the
