1.Easy
P = 75 kNABsection2 m3 m

Find the bending moment Mx at the section x = 2 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 5 mP = 75 kN at 2 mx = 2 m
Mx = kN·m
2.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)
3.Medium
w = 12 kN/mABsection4 m6 m

Find the shear force Vx at the section x = 4 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 10 mw = 12 kN/m from 0 to 10 mx = 4 m
Vx = kN
4.Medium
w = 3 kN/mABsection4 m1 m

Find the bending moment Mx at the section x = 4 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 5 mw = 3 kN/m from 0 to 5 mx = 4 m
Mx = kN·m
5.Hard
w = 5 kN/mP = 20 kNABsection1.5 m4.5 m

Find the bending moment Mx at the section x = 1.5 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 6 mP = 20 kN at 1.5 mw = 5 kN/m from 0 to 6 mx = 1.5 m
Mx = kN·m
6.Hard
w = 8 kN/mAB5 m3 m

The simply supported beam carries a uniformly distributed load over part of its span. Find the maximum bending moment Mmax in the beam.

L = 8 mw = 8 kN/m from 5 to 8 m
Mmax = kN·m

Answer key

  1. 1. Mx = 90 kN·m
  2. 2. D (x = 3 m)
  3. 3. Vx = 12 kN
  4. 4. Mx = 6 kN·m
  5. 5. Mx = 39.38 kN·m
  6. 6. Mmax = 23.77 kN·m
