Describing Different Types of Structures

[christian Bendis]

Hello all

I was wondering if someone help clear up some confusion I have regarding different type of structures.

Below are 4 x diagrams of beams:-

I have seen these types before but what confused me was that when I tried to name these types of beams I got stuck.

I would name these structures as:-

A = Cantilever Beam
B = Propped Cantilever Beam
C = No Idea???
D = Simply Supported.

How would you name these structures?

Also how would you formally define these types of structures?

I have always thought that Diagram C was simply supported????

Can anyone shed any light?

Thank you.
