Refer to the indicated problem and draw complete shear and bending moment diagrams. Show ordinates at key points and indicate magnitude of shear and moment. Neglect the beam weight
Calculate the reactions at points A and B for the beams shown.
A certain metal alloy has body centered cubic crystal structure; it has an average atomic weight of 71.2 amu; and the metal has an average atomic radius of 0.131 nm. Determine the theoretical density of this metal in grams per cubic centimetre.
What is Reynold's Number. Explain by stating the formula.
Air enters a nozzle steadily with a density of 2.5 kg/m3 and velocity of 40 m/s. It leaves the nozzle at a density of 0.81 kg/m3 and an exit velocity of 150 m/s. If the inlet area of the nozzle is 100 cm2, determine the exit area of the nozzle.
A high strength steel [E = 200 GPa] tube having an outside diameter of 80 mm and a wall thickness of 3 mm is bent into a circular curve having a 52 m radius of curvature. Determine the maximum bending stress developed in the tube
Consider the pipe and Venturi meter system shown in the three figures at a angle of 30° to the horizontal. The pipe and the Venturi meter in all three systems are identical, but the means of measuring the piezometric head (or pressure head) are diffe..
a feedwater heater extracts steam from a turbine at 600 kpa and 250degc which it combines with 0.3 kgs of liquid at 600
two thermocouples temperature measurement devices are tested by inserting their probes in boiling water recording the
what is the ratio of the flowrates through the straws? Assume the drink is viscous enough to ensure laminar flow and neglect gravity.
in a water heating system cold water at 5 c flowing at a rate of 5 kgs is mixed adiabatically with hot water at 80 c
For an initial plate temperature of Ti = 300°C, what is the rate of heat transfer from the plate? What is the corresponding rate of change of the plate temperature? The velocity of the air is much larger than that of the plate.
a two-stage cascade refrigeration system is to provide cooling at -40oc while operating the high-temperature condenser
A 90 kg pilot ejects from a plane and reaches a steady state velocity of 30 m/s with one parachute open. Neglect any air drag force on the pilot and assume that the air drag force can be modeled as an ideal damper i.e. linearly proportional to the ve..
