Moment Diagram of Cantilever Beam with Fixed End at Left hand side?

Click For Summary
The moment diagram of a cantilever beam with a fixed end on the left is identical to that with a fixed end on the right, appearing as a mirrored image. The loads and geometry remain unchanged, regardless of the viewpoint. While the shear diagram may seem different due to plotting conventions, the actual shear forces are the same in both cases. The discussion highlights a common misunderstanding regarding the representation of shear and moment diagrams. Overall, the moment remains consistent regardless of the fixed end's position.

Just want to ask if the moment diagram of Cantilever beam with fixed end at left is the same as with fixed end at right. What I mean is that they are just mirrored ? Thanks

Yes, it's exactly the same. Imagine walking around the beam and looking at it from the other side. The loads, geometry, etc. are still exactly the same, just you have moved on the other side where the fixed end appears mirrored.
 
This hints at a lack of understanding to me.

Why do you believe it would be different?
 
I just suspect that the shear diagram is difference with the two cases. but the moment is the same..
 
The shear diagram would only be different because you'd be using some convention to plot it. It only looks mirrored about the beam longitudinal axis, but is in reality the same. The shear forces would be the same, just the way they are plotted depends on the convention.
 
Thanks bda23. That's the answer I'm waiting for my confirmation. Thanks for other's idea :D
 

Thread 'What mathematics software should engineering students use?'

What mathematics software should engineering students use? Is it correct that much of the engineering industry relies on MATLAB, making it the tool many graduates will encounter in professional settings? How does SageMath compare? It is a free package that supports both numerical and symbolic computation and can be installed on various platforms. Could it become more widely used because it is freely available? I am an academic who has taught engineering mathematics, and taught the...
