Determine the structural loads in truss members AD, AE, BE, CD, CE, and DE. b) Assuming that the truss members will all be constructed of 4130 alloy steel tubing, propose a cross-sectional geometry for each truss member that provides the following safety factors (FoS) - FoS of at least 3 against yielding, and - FoS of at least 1.5 against buckling. The cross-sectional geometry must be of standard stock sizes readily available from suppliers, such as OnlineMetals. c) Calculate the actual FoS for outer truss sections under the maximum defined loads based on your geometry selection(s). d) Estimate the material cost per truss sub-se

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
