1.Easy
6 kN/mABCDEFG1 m1 m1 m1 m1 m1 m

The marks A to G split the beam into six equal parts. At which mark is the bending moment largest in size, sagging or hogging? Click it in the diagram.

6 kN/m, 0–5 m
  1. 1A (x = 0 m)
  2. 2B (x = 1 m)
  3. 3C (x = 2 m)
  4. 4D (x = 3 m)
  5. 5E (x = 4 m)
  6. 6F (x = 5 m)
  7. 7G (x = 6 m)
2.Easy
w = 10 kN/mAB5 m

The cantilever is fixed at A and carries a uniformly distributed load w over its whole length. Find the shear force VA at the fixed support A. Use sagging moments positive and upward shear on the left face positive.

L = 5 mw = 10 kN/m from 0 to 5 m
VA = kN
3.Medium
M0​ = 25 kN·mAB3.5 m1.5 m

The simply supported beam carries a clockwise couple M0 = 25 kN·m at x = 3.5 m from A, and no other load. Find the bending moment Mx just to the right of the couple. Use sagging moments positive and upward shear on the left face positive.

L = 5 mM0 = 25 kN·m clockwise, at 3.5 m
Mx = kN·m
4.Medium
w = 12 kN/mABsection3 m1 m

Find the bending moment Mx at the section x = 3 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 4 mw = 12 kN/m from 0 to 4 mx = 3 m
Mx = kN·m
5.Hard
w = 4 kN/mP = 50 kNABsection2.5 m1 m0.5 m

Find the bending moment Mx at the section x = 3.5 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 4 mP = 50 kN at 2.5 mw = 4 kN/m from 0 to 4 mx = 3.5 m
Mx = kN·m
6.Hard
w = 6 kN/mP = 35 kNAB9 m1 m

The simply supported beam carries a uniformly distributed load w over its whole span and a point load P. Find the maximum bending moment Mmax in the beam.

L = 10 mP = 35 kN at 9 mw = 6 kN/m from 0 to 10 m
Mmax = kN·m

Answer key

  1. 1. D (x = 3 m)
  2. 2. VA = 50 kN
  3. 3. Mx = 7.5 kN·m
  4. 4. Mx = 18 kN·m
  5. 5. Mx = 19.13 kN·m
  6. 6. Mmax = 93.52 kN·m
