    Bending Moments
AI Thread Summary
The discussion focuses on understanding bending moment diagrams and shear force diagrams in the context of a school assignment. The user seeks assistance after missing a lesson that covered a new type of question involving bending moments without provided reactionary forces. Key principles mentioned include the equilibrium conditions for beams, specifically that the sum of forces in both the x and y directions must equal zero, along with the sum of moments about any point. A suggestion is made to sum moments about one end of the beam to find the reaction at the other end. The user is encouraged to share their work for further guidance.

Bending moments Help!

Hi guys, didnt really know how the layout of a bending moment diagram would fit under the standard template provided so i'll have a bash at explaining the problem.

On my school course i have been doing bending moments/diagrams and shear force diagrams, but a few days ago we were given a new type of question without the reactionary forces provided and as i had an urgent dentist appointment i missed the lesson...we are not off college for 2 weeks and i was wondering if you could be of some help if i posted an image of the question - thus giving me a better idea and understanding of how to answer the question.

i have attached the image of it.

thanks.

For a beam in equilibrium,
- the sum of all forces in the y direction must equal zero
- the sum of all forces in the x direction must equal zero, which is not required for this problem
- the sum of all moments about any point must equal zero

Try summing moments about one end, to determine the reaction at the other end. Please show an attempt at your work.
