1.	For which one of the following loading conditions is the standard endurance strength. multiplied by a load factor, Ke = 0.9? (a) Reversed beam bending loads (b) Reversed axial load with no bending (c) Reversed axial loads with intermediate bending (d) Reversed torsion loads
Answer» (c) Reversed axial loads with intermediate bending. For bending complete reversed, k_c = 1 For axial complete reversed, k_c = 0.74 Hence, (c), k_c ≈ 0.9 For mix bending and axial.

For which one of the following loading conditions is the standard endurance strength. multiplied by a load factor, Ke = 0.9? (a) Reversed beam bending loads (b) Reversed axial load with no bending (c) Reversed axial loads with intermediate bending (d) Reversed torsion loads

Answer»

(c) Reversed axial loads with intermediate bending.

For bending complete reversed, k_c = 1

For axial complete reversed, k_c = 0.74

Hence, (c), k_c ≈ 0.9

For mix bending and axial.
