1) Describe the kutta condition.
2) Describe how lift is generated by an airfoil impulsively starting from rest.
A hydraulic shear applies 2000 lb force to a wedge. It is used to shear plate steel to rough size. The shear has a 1/4 inch thick cutting blade with a 45 degree slope. What is the ideal mechanical advantage of the wedge?
Mainframe computing used to be the only way to manage enterprise data. Then personal computers changed the data management scene. How do these two computing styles differ, and how did shift to PC-based computing evolve.
your job is to create a design of Rankine cycle that create the most possible power from this heat source . you may use any working fluid for which you can find the properties , assume the turbines 92% efficient and pumps 85%
Show the principle stresses on the neutral axis on a correctly oriented element relative to the axis of the beam.
The maximum take-off mass of an Airbus A380 passenger jet is about 600 000 kg. The lift is provided by the wings, which have a total area of 845 m2.
what is the specific heat of air in US customary units given that its value in SI units is approximately 1 kN.m/kg.K?
Motor M draws in the cable with an acceleration of 4 ft/s2, measured relative to the 200-lb mine car. Determine the acceleration of the car and the tension in the cable. Neglect the mass of the pulleys.
A short 60-mm-diameter circular bar is made of a material for which the maximum safe compressive stress is 80 MPa and the maximum safe shearing stress is 30 MPa. Determine the maximum axial compressive force that can be safely applied.
Model the earth as a sphere with a diameter of 8,000 miles. Using 14.7 psia as the average pressure at the earth's surface and ignoring variation in g with altitude, estimate the weight of the earth's atmosphere in lbf, and its mass in lbm.
Verify that heating the wire may be treated as a lumped-capacity process, find the steady-state temperature of the wire and find how long it takes for the temperature of the wire to reach 100°C.
Find the approximate location of the laminar turbulent transition - what is the net heat removed by the air around the rod?
