There is a reason why bending moment are taught in the first weeks of an engineering degree. Their importance and understanding is crucial for any engineer. This video intuitively explains what bending moments actually represent in an engineering context. The video uses only simple examples and avoids and use of any mathematics. Bending and shear diagrams are not covered in this video since the purpose is to build intuition rather than computational skills.
