An engineer who is studying the tensile strength of a steel alloy knows that tensile strength is approximately normally distributed with sigma= 60 psi. A random sample of 12 specimens has a mean tensile strength of 3450 psi. a) Compute a two-side confidence interval on the maen tensile strength at a 95% confidence level. b) Test the hypothesis that the mean strength is 3500 psi at alfa=0.05, and provide a conclusion statement. c) If we keep the signifiance level constant...

At a point in a stressed body, the principal stresses are 100 MN/m2 (tensile) and 60 MN/m2 (compressive). Determine the normal stress and the shear stress on a plane inclined at 50degree counter clockwise to the axis of minor principal stress. Also, calculate the maximum shear stress at the point and draw the Mohr’s stress circle to verify the answers. If the yield strength and Poisson’s ratio of the material in the above case is 240 MPa and 0.3 respectively,...

Though steel have high tensile strength, detailing is necessary not only for the steel structures but also for the RCC members as it is the translation of all the mathematical expression’s result. For that matter, coin a comprehensive definition for detailing of reinforcement bar (steel).

Exercise 6.5 Compute the stresses in laminate coordinates at top and bottom of each lamina in Example 6.1 (p. 178) when the laminate is subjected to ?0x = 765(10?6) mm/mm, ?0y = ?280(10?6) mm/mm, ?xy = 34.2(10?6)1/mm and all remaining strains and curvatures equal to zero. Note: this is Example 6.1 Compute the coefficients in the plate stiffness equations (6.9) for a two- lamina laminate with ?1 = 55?, ?2 = ?55?, t1 = t2 = 0.635 mm with material...
