Problem a) – c): Use the method of joints, the method of sections, or both to solve the following trusses. Draw F. B.Ds for all your calculations. 1) Identify all the zero force members in the trusses; 2) Calculate the reactions at the supports; 3) Determine the internal forces for marked members in each truss; 4) Indicate your final results on the truss system.

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

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.

How to increase the thermal officiency of an ideal simple rankino cycle? among these methods, which one is the best and why?
