a. King post truss
b. Queen post truss
c. Scissor Truss
d. Pyramid Truss

Answer:

A truss with two principal rafters, a tie beam, and a central vertical post is known as a King Post Truss.

The truss described in the question seems to be a King Post Truss. A King Post Truss primarily consists of two principal rafters, a tie beam, and a central vertical post, which is also known as the king post. In some cases, it might also make use of two angled struts for additional support. This design differs from a Queen Post Truss (which uses two vertical posts), a Scissor Truss (where the rafters cross each other), or a Pyramid Truss (a complex design used for large spaces).

The King Post Truss is a simple and traditional type often used in residential building and small-scale structures due to its simplicity and efficiency. It's most effective for spans up to 8 meters (approximately 26 feet) and provides an effective way to carry the load of a roof to the walls of a structure without needing large, load-bearing walls.
