Understanding Trusses

Why is a triangle considered a stable shape for trusses?

• Because its angles remain constant if the sides are fixed

• Because it has four sides

• Because it is the simplest shape

• Because it can change angles easily

What is a planar truss?

• A truss with members in different planes

• A truss analyzed as a two-dimensional structure

• A truss used only in bridges

• A truss that cannot carry loads

Which truss design is more cost-effective due to its tension and compression arrangement?

• Fink truss

• Warren truss

• Howe truss

• Pratt truss

What is a key advantage of the Warren truss design?

• It has no members in compression

• It uses equilateral triangles for uniformity

• All members are of different lengths

• It uses more members than other designs

In the Howe truss, which members are typically in compression?

• All members

• Diagonal members

• Horizontal members

• Vertical members
