The Cramster solution uses a formula that the book derived form the circle. however the point of this exercise was to use Mhor's circle to arrive at the answer, not a formula.
The cable's direction is {1.00i - 1.00j - 1.00k} and it has a tension of 165lb. What is M_a ( the moment that tends to twist the telephone pole due to the tension in the cable applied at point B?)
Mixture of saturated liquid and saturated vapor of substance water at 95oC enters steady flow adiabatic compressor and undergoes an isentropic process. Substance water leaves the compressor at press
Calculate the "minimum" power for this process. Do the same for 1 mol/s of O2. Use reasonably accurate data for this problem. How would this compare to the "maximum" power for these processes?
Determine the pressure p2 and p3 in pipes 2 and 3 under the assumptions that the flow rates dived evenly between pipes 2 & 3.
A linear bearing supports a load W, has a contact area A and travels at a maximum velocity V. What expression will be used to select possible bearing materials for the application?
An elevated open stairway (like the one in the SAC!) is designed to be supported by four steel rods connecting the stairway to the ceiling. The weight of the stairway plus a full load of people is 9
Ten kilograms of ice at 260 K is duped into 20 kg of liquid water initially at 300 K in an insulated container. Calculate Final temperature in degrees C.
A power drive shaft is designed with a safety factor of 8. The shaft is subjected only to torsional load (torque). If the shaft length is doubled, what is the new safety factor?
A boring bar 1 inch in diameter extends 2 inches from the tool post. When the bar is subjected to a machining force (applied at the end of the bar and perpendicular to the axis of the bar) it is obs
A vessel contains 4 kg of wet steam (liquid-vapor mixture) at 140 degC. After the addition of heat, the steam has a pressure of 0.6 MPa and a temperature of 700 deg.
An insulated piston-cylinder device contains 0.05m3 of saturated refrigerant-134A vapor at 0.8mPa pressure. The refrigerant is now allowed to expand in a reversable manner until the pressure drops t
Plot the magnitude of the velocity of the parasailer as a function of q, determine the total acceleration of the parasailer at t= 5 sec.
A design specification requires that a 1008 pound vehicle be able to climb a 38 degree incline at 43 mph. What is the minimum horsepower required of its engine?
The Department of Energy projects that between the yeras 1995 and 2010, the United States will need to build new power plants to generate an additional 150,000 MW of electricity to meet the increasi
Boltzmann's constant is equal to 11.7 x 10^-8 cal/(cm2dk4). Write a vba statement to assign the value of boltzmann's constant in scientific notation to a variable sigma.
An airplane has a rectangular-platform wing that has an elleiptical spanwise lift distribution. the airplane has a mass of 1200 kg, a wing area of 20 m^2, and a wingspan of 14 m, and it is flying at
If the pressure distribution over the surface of the body is constant (e.g. atmospheric pressure everywhere), use Gauss' theorem to prove that the resultant surface force (force due to pressure) on
A flat plate separates two supersonic air flows. The flow along the upper surface has a Mach number of 1.4 and a stagnation pressure of 55.3 psia. The flow along the lower surface has a Mach number
As the argon passes through the pipe, it is heated in a steady flow process to 100 degrees C. The pressure at that point is 28 kPa. No work is being done. Calculate the rate of heat transfer (Q).
A two-dimensional, diamond shaped supersonic airfoil has a total inclued angle of 15 degrees at its leading edge and its trailing edge. The maximum thickness of the airfoil is 0.5 ft.
