A disk cam drives a radial flat-faced follower with simple harmonic motion. The follower moves out and back in one revolution of the cam. If the total displacement is 50 mm and the minimum radius 25 mm, determine the parametric (x and y) equations of the cam contour. Eliminate the parameter lo obtain the equation of the curve, which is the cam contour. Delem1ine the theoretical length of the follower face.
a spherical balloon filled with heliumm is initially at 300 k and 100 kpa with a diameter of 5 cm. the balloon is
An inventor claims to have developed a power cycle operating between hot and cold reservoirs at 1175 K and 295 K, respectively, that provides a steady-state power output of (a) 28 kW, (b) 31.2 kW, while receiving energy by heat transfer from the hot ..
Determine from these data, with the aid of dimensional analysis, the relationship between θ, 0, and ω for this particular apparatus. Hint: Plot the data using appropriate dimensionless parameters, and determine the equation of the resulting curve ..
Consider the conditions of Example 9.3, including the effect of adding insulation of thickness t and thermal conductivity k = 0.035 W/m · K to the duct. We wish to now include the effect of radiation on the outer sur- face temperatures and the tot..

A turbine receives air at 1500 K, 1000 kPa and expands it to 100 kPa. The turbine has an isentropic efficiency of 85%. Find the actual turbine exit air temperature and the specific entropy increase in the actual turbine.
A gas in a piston-cylinder assembly undergoes an expansion process for which the relationship between pressure and volume is given by pV^n = constant. The initial pressure is 4.25 bar, the initial volume is 0.25 m^3 and the final volume is 0.55 m^3.
if p 400 and the coefficient of kinetic friction between the 50- crate and the inclined plane is 0.25 determine the
