heat transfer Consider the picture shown below. The very long cylindrical rod (surface 1) acts as a black surface 1 m in diameter which is maintained at 1000 K. The rod is surrounded by a very thin cylindrical shield with inner surface 3-1 and outer surface 3-2. The diameter of this shield is 2 m; and is so thin that the inner and outer surface areas are essentially the same. The shield has an emissivity of 0.3 on both sides....
Question 2 The cylindrical pressure veese shown in the figure has an inside diameter of 910 mm and a al thickness of 10 mm. The cylinder is made of an aluminum alloy that has an elastic modulus of E = 70 GPa and a shear modulus of G = 27.0 GPa mounted on the exterior surface of the cylinder at right angles to each other. The angle θ is 28°. If the pressure in the vessel is 1.69 MPa. determine:...
Consider the structure shown in the figure below. The cylinder (6 ft in diameter) is supported by two plates connected by pins. The total weight of the cylinder is 15,000 lb. Find the shear stresses at pin A and B. The diameter of all pins is 1 inch. Assume the plates are weightless and very smooth without any friction. 15 k

A device for sampling water in lakes and streams consists of a 2.25 cm diameter cylindrical tube that is 3 cm in length. The disks are placed in a wan technician to insert the sampling disk into the water. The tubes are then sealed in a container and taken back to the lab where the water is removed from the tube and analyzed. The tube is made of glass and contains 200 cylindrical pores 1 mm in diameter that run...
The cylindrical pressure vessel shown in the figure has an inside diameter of 980 mm and a wall thickness of 12 mm. The cylinder is made of an aluminum alloy that has an elastic modulus of E = 72 GPa and a shear modulus of G = 27.5 GPa. Two strain gages are mounted on the exterior surface of the cylinder at right angles to each other. The angle θ is 21°. If the pressure in the vessel is 1.86...

The Part A d density of ocean water is p, 1024 kg/m", and the denslity of the er extends h 3 m above the ocean's surface, determine the depth of the cylinder below the surface If the cyinde Express your answer to three significant figures and include the appropriate units ce is p, 935 kg/m dValue...
Problem 1 {12} Consider the test arrangement shown in the figure below. In this arrangement, a compressive load, P, is applied on a concrete cylinder that rests on plate and roller supports as shown in the figure. The plate and rollers can be assumed rigid with infinite strength. The rollers in turn apply four- point flexural load on a concrete beam underneath, which is simply supported on a hinge at the left end and a roller on the right end....
--Trunnion Clevis Problem II (10 Marks) For the shown trunnion mounted hydraulic cylinder, the internal diameter of the cylinder is 75 mm and the maximum operation pressure is the cylinder is 25 MPa. The pistion rod is made of steel 40Cr1 (Sy = 530 MPa and E=207 GPa). For buckling considerations, the effective length of the psiton rod is considered as the distance between the trunnion and the clevis-mount, when the piston rod is extended to its full working stroke...
