A circular cone with semi-angle α is fixed with its axis of symmetry vertical and its vertex O upwards. A second circular cone has semi-vertical angle (π/2)-α and has its vertex fixed at O.
The second cone rolls on the first cone so that its axis of symmetry precesses around the upward vertical with angular speed λ. Find the angular speed of the rolling cone.
Piston-cylinder device contains 0.2kg of water initially at 800 kPa and 0.06m^3. Now 200 kJ of heat is transferred to the water while its pressure is held constant. Determine the final temperature of the water. Also, show the process on a T-v d..
Derive an equation that relates the measured potential of the cell in (b) to pAsO4 (assume that the junction potential is zero).
A cylindrical oil-storage tank, whose diameter is 120 ft, is 60 ft deep when it is fully filled with an oil of density 55lbm/ft³. Its top is open to the atmosphere. What is the gauge pressure (psig) at the bottom of this tank?
A constant pressure is applied to a 0.5 m diameter vertical cylinder of 300 kPa in a piston cylinder device. Atmospheric pressure is 100 kPa. Calculate the mass of the piston and the work needed to move the piston 5 m in the upward direction.
Knowing that the coefficient of static friction is 0.30 and that the brake drum is rotating counterclockwise, determine the minimum value of α for which the brake is not self-locking.
The following is a diagram shows refraction of a light beam at the interface of two media. The incidence and refraction angles are measured to be 45 deg and 30 deg respectively. Will total reflection happen when the light beam shins from the top to t..
The road surface varies sinusoidally with an amplitude of and a wavelength of 6 m. Write a MATLAB program to find the displacement amplitude of the automobile for the following conditions
When a material is subjected to a cyclic stress, large cracks grow more slowly than small cracks. The concept of a critical stress for crack propagation is only applicable to brittle materials. Materials will not break if the applied stress is kept b..
If it is necessary to maintain a pressure of 180 psi at the snow-making machine, determine the horsepower added to the water by the pump. Neglect minor losses.
a 10-kg block is moving down along a plane incline at a 10 degree angle. the coefficient of kinetic friction between
Using the thermodata computed from the matlab functions to compute the mixture-averaged mass specific Gibbs free energy of the final mixture, as a function of the progress variable (normalized as: 0 for no dissociation, and 1 for complete dissociatio..
