A transverse load of \( 20 \) kN acts \( 60 \) mm from the shear centre of a section. The equivalent torque is

  • A.0.33 kN m
  • B.120 kN m
  • C.1.2 kN m
  • D.12 kN m

Answer: C

Correct answer: 1.2 kN m

\[ T = P e = 20 \times 0.06 = 1.2\ \mathrm{kN\,m}. \] Any transverse load not passing through the shear centre is statically equivalent to the same load at the shear centre plus this torque, and the section is then analysed for bending and torsion separately and the results superposed.
