The critical stress value of a column subjected to tensile axial load can be det

Question

The critical stress value of a column subjected to tensile axial load can be determined using the Euler equation for the short columns failure occur essentially as a result of yield stress. As the stress concentration factor decreases, the fatigue life also decreases. The slope of the S-N curve is negative. Endurance stress value is approximately equal to half of the yield tensile strength Goodman equation is valid only when a time history has tensile mean stress values for completely reversed loading R=0.1.

Explanation / Answer

1.true ....euler equation is valid for columns.

2., false

3 false

4.false i..it decreases and then remains constant

5.false that depens on material

6.true

7 false
