Section forces for beams with point loads

Question 1

What 3 section forces does a beam have at any point?

Answer 1

• normal force, N, parallel the beam
• shear force, V, perpendicular to the beam
• bending moment, M

Question 2

Consider a simply supported beam ACB, subjected to a point loads of 120kN vertically downwards, as shown. Calculate the section forces at point C for the simply supported beam

Answer 2

Question 3

Consider a simply supported beam ACB, subjected to a point loads of 120kN vertically downwards, as shown. Calculate the section forces at point C for the simply supported beam

Answer 3
