The correct answer is: C. King post truss
A king post truss is a type of truss that is commonly used in buildings with spans of 6 to 9 meters. It is a simple and efficient design that is strong and stable. The truss consists of two main vertical posts, or king posts, that support a horizontal beam, or collar beam. The collar beam is supported by a series of diagonal braces, which help to distribute the weight of the roof evenly.
Mansard trusses are a type of truss that is commonly used in roofs with a steep pitch. They are made up of two main diagonal rafters, or mansard rafters, that support a horizontal beam, or collar beam. The collar beam is supported by a series of vertical posts, or posts, which help to distribute the weight of the roof evenly.
Queen post trusses are a type of truss that is commonly used in roofs with a moderate pitch. They are made up of two main vertical posts, or queen posts, that support a horizontal beam, or collar beam. The collar beam is supported by a series of diagonal braces, which help to distribute the weight of the roof evenly.
Collar trusses are a type of truss that is commonly used in roofs with a low pitch. They are made up of two main horizontal beams, or collar beams, that are supported by a series of vertical posts, or posts. The collar beams are connected by a series of diagonal braces, which help to distribute the weight of the roof evenly.
King post trusses are the most efficient type of truss for spans of 6 to 9 meters. They are strong and stable, and they can be easily adapted to different roof pitches.
