1.Easy

The cantilever is fixed at A and carries a uniformly distributed load w over its whole length. Find the bending moment M_x at the section x = 3 m from the fixed 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

M_x = kN·m

2.Easy

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.

15 kN @ 4 m

1A (x = 0 m)
2B (x = 1 m)
3C (x = 2 m)
4D (x = 3 m)
5E (x = 4 m)
6F (x = 5 m)
7G (x = 6 m)

3.Medium

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

L = 6 mw = 6 kN/m from 0 to 6 mx = 1.5 m

V_x = kN

4.Medium

Find the bending moment M_x at the section x = 1 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 5 mw = 2 kN/m from 0 to 5 mx = 1 m

M_x = kN·m

5.Hard

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

L = 4 mw = 10 kN/m from 1 to 3 m

M_max = kN·m

6.Hard

Find the bending moment M_x 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 = 40 kN at 1.5 mw = 4 kN/m from 0 to 4 mx = 3.5 m

M_x = kN·m

Answer key

1. M_x = −6 kN·m
2. E (x = 4 m)
3. V_x = 9 kN
4. M_x = 4 kN·m
5. M_max = 15 kN·m
6. M_x = 11 kN·m
