Prismatic Beam

A prismatic beam is a structural element that has a uniform cross-section along its length. This means that the beam has the same depth, width, and strength throughout its length.

Uniform Cross-Section

The correct option for a prismatic beam is 'D', which states that it has a uniform cross-section. A uniform cross-section means that the beam has the same dimensions (depth and width) and material properties (strength) at every point along its length.

Importance of Uniform Cross-Section

A uniform cross-section is important for the structural integrity and stability of the beam. It ensures that the beam can withstand the loads and forces that are placed upon it without experiencing any significant bending, deformation, or failure.

Applications of Prismatic Beam

Prismatic beams are commonly used in construction and engineering applications, such as bridges, buildings, and other structures. They are typically made from materials such as steel, concrete, or timber and are designed to support a range of loads, including dead loads (the weight of the structure itself) and live loads (people, furniture, equipment, etc.).

Conclusion

In conclusion, a prismatic beam has a uniform cross-section, which means that it has the same depth, width, and strength at every point along its length. This is important for the structural integrity and stability of the beam and is commonly used in construction and engineering applications.
