1.Easy
P = 65 kNABsection2.5 m2.5 m

Find the bending moment Mx at the section x = 2.5 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 5 mP = 65 kN at 2.5 mx = 2.5 m
Mx = kN·m
2.Easy
P = 20 kNABsection2 m2 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 = 4 mP = 20 kN at 2 mx = 2 m
Mx = kN·m
3.Medium
w = 8 kN/mABsection1.5 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 mw = 8 kN/m from 0 to 6 mx = 1.5 m
Mx = kN·m

5.Hard
w = 8 kN/mP = 10 kNABsection7 m3 m

Find the bending moment Mx at the section x = 7 m from support A. Use sagging moments positive and upward shear on the left face positive.

L = 10 mP = 10 kN at 7 mw = 8 kN/m from 0 to 10 mx = 7 m
Mx = kN·m
6.Hard
w = 12 kN/mAB4 m2 m2 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 = 12 kN/m from 4 to 6 m
Mmax = kN·m
