Create a 60 degree inclined plane utilizing various building components, string, as single pulley , and a scientific mass. attach one end of the string to the scientific mass (resistance force) and the other end to a force-measuring device. Place the scientific mass on the inclined plane and string over the pulley. Using a force-measuring device, pull the string and determine the force needed to obtain static equilibrium.
b. calculate the ideal mechanical advantage of the inclined plane system described above.
c. Calculate the ideal effort force needed to overcome the known resistance force.
Seawater flows steadily into an open 100 liter tank initially filled completely with freshwater. The freshwater mixes thoroughly with the seawater and the mixture overflows out of the tank.
horizontal pipe, and the fanning friction factor is f_F = 0.0060. what error in the pressure drop would ensue if the assumption were made that the flow was laminar, abandoning the previous value of the friction factor.
Two m^3 of xenon(Xe) are contained in a closed rigid tank at 70 degree C and 2 bar. The tank is heated to a pressure of 10 bar. Assuming that Xe behaves like an ideal gas with a specific heat ration of 1.7
Find the maximum shearing stress and its location in the shaft and the angle of twist of A with respect to C. Let G = 4x10^6 psi for the entire shaft.
If the pH of a natural water is 7.8, and the alkalinity was measured to be 125 meq/L, determine the following: - Alkalinity as mg/L CaCo3 - Approximate the total carbonate concentration (Ct), in moles per liter.
what are the three meterials based on the predominant types of bond and what are the predominant types of bond in each category
