A three-point transverse bending test is conducted on a cylindrical specimen of aluminum oxide having a reported flexural strength of 390 MPa. If the specimen radius is 2.5 mm and the support point separation distance is 30 m, predict whether the specimen will fracture or not when a load of 620 N is applied. Justify your prediction.

An acetal polymer block is fixed to the rigid plates at its top and bottom surfaces. If the top plate displaces 5 mm horizontally when it is subjected to a horizontal force P = 2 kN, determine the shear modulus of the polymer. The width of the block is 100 mm. Assume that the polymer is linearly elastic and use small angle %3D analysis.

Please show your solution and write clearly.

If the maximum force one bolt can withstand is 32505 lbf, how many bolts can be removed from the pressure vessel at the given conditions before the end cap blows off?

5. The following table shows data from a flow study of a PS melt at 210°C in a capillary rheometer. a. Make a plot of log shear stress versus log shear rate. b. Calculate the value of the viscosity at 1 and 135 s', respectively. Shear Stress ,(10° dyn/cm') Shear Rate, 3.5 1.0 12.0 5.0 20.0 12.2 33.0 25.0 40.0 52.5 60.0 135.0 69.8 400.0

For the edge dislocation, cite the relationship between the direction of the applied shear stress and the direction of dislocation line motion. O Neither parallel nor perpendicular O Parallel O Perpendicular

(3) We are offered some pipes made of a new kind of plastic. To test their roughness, we pump water through a 0.0762 m pipe made of this material at an average velocity of 12.19 m/s. The observed Fanning friction factor is 0.0032. Estimate the absolute roughness of this plastic.

Question: A cylindrical rod of 1040 steel originally 11.4 mm (0.45 in.) in diameter is to be cold worked by drawing;  the circular cross section will be maintained during deformation.  A cold-worked tensile strength in excess of 825 MPa (120,000 psi) and a ductility of at least 12%EL are desired.  Furthermore, the final diameter must be 8.9 mm (0.35 in.).  Explain how this may be accomplished.
