Definition of an Overhanging Beam:
An overhanging beam is a type of structural element that extends beyond its support at one or both ends. It is similar to a cantilever in that it has a protruding section, but it is not exactly the same.
Explanation:
To better understand the concept of an overhanging beam, let's break down the question and its options:
A) Same as Cantilever:
This option suggests that an overhanging beam is identical to a cantilever. While there are similarities between the two, they are not exactly the same. Both involve a beam that extends beyond its support, but a cantilever refers specifically to a beam that extends from a fixed point and is supported only at one end.
B) Not the same as Cantilever:
This option correctly states that an overhanging beam is not the same as a cantilever. As mentioned above, a cantilever is a specific type of overhanging beam, but not all overhanging beams are cantilevers.
C) Extends beyond its support at either end:
This option accurately describes an overhanging beam. It means that the beam extends beyond its support at one or both ends. In other words, the beam hangs over the edge or extends past the point where it is supported, creating an overhanging section.
D) Extends beyond its support at both ends:
This option incorrectly suggests that an overhanging beam extends beyond its support at both ends. However, this is not the case. An overhanging beam can extend beyond its support at one end or both ends, but it is not necessary for it to extend beyond both ends.
Therefore, the correct answer is Option C: One which extends beyond its support at either end.
