At a point in a structural member, yielding occurs under a state of stress given by 0 40 0 40 50 -60 MPa 0 -60 0 Determine the uniaxial tensile yield strength of the material according to the maximum distortion energy theory. What is the octahedral shear stress at this point? Compare this octahedral shear stress with the maximum shear stress that develops under uniaxial tension when the material reaches its uniaxial tensile yield strength.

Consider a 50-cm-diameter and 95-cm-long hot water tank. The tank is placed on the roof of a house. The water inside the tank is heated to 808C by a flat-plate solar collector during the day. The tank is then exposed to windy air at 188 C with an average velocity of 40 km/h during the night. Estimate the temperature of the tank after a 45-min period. Assume the tank surface to be at the same temperature as the water inside, and the heat transfer coefficient on the top and bottom surfaces to be the same as that on the side surface. Evaluate the air properties at 508C

There are numerous occasions in which a fairly uniform free-stream flow encounters a long circular cylinder aligned normal to the flow. Examples include air flowing around a car antenna, the wind blowing against a flag pole or telephone pole, wind hitting electrical wires, and ocean currents impinging on the submerged round beams that support oil platforms. In all these cases, the flow at the rear of the cylinder is separated, unsteady, and usually turbulent. However, the flow in the front half of the cylinder is much more steady and predictable. In fact, except for a very thin boundary layer near the cylinder surface, the flow field may be approximated by the following steady, two-dimensional velocity components in thexyorrplane:u r=Vcos(1 r 2a 2),u =Vsin(1+ r 2a 2)4. Show that the acceleration is (you are allowed to use a symbolic software to simply, show proof that you used it):a=2 r 3a 2V 2(1 r 2a 22sin 2) e^r+2V 2r 3a 2sin2 e^5. Determine if the fluid is accelerating on the surface of the cylinder. If so, in what direction? Consider the following angles=0,/2,,3/2Note that on the surfacer=a. 6.

A thin plate . moves between two parallel, horizontal, stationary flat surfaces at a constantvelocity of V m/s. The two stationary surfaces are spaced 8 cm apart, and the medium betweenthem is filled with oil whose viscosity is 0.9 Ns/m2. The part of the plate immersed in oil atany given time is 2-m long and 0.5-m wide. If the plate moves through the mid-plane betweenthe surfaces, determine the force required to maintain this motion.. water=1000 kg/m3. g=9.81m/s2v=10.5 m/s.
