a compound cylinder is to be made by shrinking one tube on to another so that the radial compressive stress at the junction is 28.5 N/mm2. if the outside diameter is 26.5 cm and the bore 12.5 cm, calculate the allowable for shrinkage at the common diameter, which is 20 cm. E = 2.1×105 N/mm2 ?
The machine component shown has a rectangular cross section with a depth of d = 3.250 in. and a thickness of 0.625 in. The component is subjected to a tension load of P = 7.4 kips. A milling operation will be used to remove a portion of the cross section in the central region of the component. If the allowable tension stress at section a-a must be limited to 55 ksi, determine the maximum depth of cut y that is permissible. d Answer: Ymax = a in. Ans - 2inches

14.30 (B). A certain equiangular strain gauge rosette is made up of three separate gauges. After it has been installed it is found that one of the gauges has, in error, been taken from an odd batch; its gauge factor is 2.0, that of the other two being 2.2. As the three gauges appear identical it is impossible to say which is the rogue and it is decided to proceed with the test. The following strain readings are obtained using a gauge factor setting on the strain gauge equipment of 2.2: Gauge direction Strain x 10-6 0° 60° 120° +1 -250 + 200 Taking into account the various gauge factor values evaluate the greatest possible shear stress value these readings can represent.

1- In drilling a 9 5/8" hole, the used weight is 3000 lb/inch of bit diameter. If 75% of drill collars should be in compression, find the necessary number of joints of drill collar needed. Drill collars used have 6 " OD and 2 ½" ID and 134 kg/Mt. nominal weight. Air is used as a drilling fluid.
Question 2 An onshore rig is drilling a production well with drilling pipe with the dimension of 250 mm outer diameter and 130mm inner diameter, see Figure 2. When drilling the drilling pipe, suddenly hit a bedrock which cause the drilling operation stop, see Figure 2. The drilling pipe is made of steel with the modulus of elasticity of 200 GPa and coefficient of thermal expansion is 11.7x10-6/0C. Assuming the initial temperature of the drilling pipe is 27°C and final drilling pipe temperature is 80°C, compute: a) the reaction force at point A and B 130mm Tracing h Snel S 250mm Kelly Sandstone 3500m b) Normal stress exhibit by the drilling pipe c) Is normal stress exhibit compression or tension? 2cm Bedrock 500m F000kN

1. (e) One of the limitations of extending axis translation technique for measuring negative pore water pressure using null type pressure plate is: (i)Air diffusion occurs through the ceramic disk when the axis translation test is performed for a long time period. (ii) Water losses from specimen when the test is performed for a long time period. (iii) Secondary consolidation arises when test is performed for a long period of time (iv) All the above (a, b and c) (v) None of the above The ceramic disk used in the null pressure plate apparatus does not allow the air to flow; however, free flow water is possible. Explain the mechanism associated with this behavior. If the purpose of ceramic disk is not to allow the air out from it; how can the air come out from the specimen? What will be the impact of such a phenomenon?
