A 100-mmmm long rod has a diameter of 15 mmmm. If an axial tensile load of 145 kNkN is applied, determine its change in length. Assume linear-elastic behavior with E� = 200 GPaGPa.

A hallow cylindrical steel column with an outer diameter of 200 mm and an inner diameter of 180 mm is subjected to a compressive load of 200 kN. The yield strength of the steel is 250 MPa. Calculate the factor of safety for the column using the maximum normal stress theory.

Need asap A round brass rod 30 mm in diameter and 200 mm long is subjected to a compressive force of 100 kN. If μ = 0.33 and E = 105 GPa. Determine the change in diameter. In mm. Thanks

7 ft 5 ft The assembly shown above includes column AB, which has the following properties: Pinned (top and bottom) for buckling about x-axis Free at top and fixed at bottom for buckling about y-axis Circular cross-section with 8-inch diameter E = 10000 ksi Which of the following is closest to the critical buckling force of column AB? O Per = 269 kip O Per = 1080 kip O Per = 538 kip O Per = 135 kip
