1.Easy
w = 10 kN/mABsection1 m1.5 m

The cantilever is fixed at A and carries a uniformly distributed load w over its whole length. Find the bending moment Mx at the section x = 1 m from the fixed support A. Use sagging moments positive and upward shear on the left face positive.

L = 2.5 mw = 10 kN/m from 0 to 2.5 mx = 1 m
Mx = kN·m
2.Easy
10 kNABCDEFG1 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.

10 kN @ 3 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
P1​ = 65 kNP2​ = 55 kNAB1 m4 m3 m

The simply supported beam carries two point loads. Find the maximum bending moment Mmax in the beam.

L = 8 mP1 = 65 kN at 1 mP2 = 55 kN at 5 m
Mmax = kN·m
4.Medium
w = 5 kN/mABsection3.5 m2.5 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 = 6 mw = 5 kN/m from 0 to 6 mx = 3.5 m
Mx = kN·m
5.Hard
w = 6 kN/mP = 25 kNABsection1.5 m1.5 m1 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 = 4 mP = 25 kN at 3 mw = 6 kN/m from 0 to 4 mx = 1.5 m
Mx = kN·m
6.Hard
w = 5 kN/mP = 55 kNABsection4 m1.5 m2.5 m

Find the bending moment Mx at the section x = 5.5 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 8 mP = 55 kN at 4 mw = 5 kN/m from 0 to 8 mx = 5.5 m
Mx = kN·m
