Torsional twist
Bending
Buckling
Beams are characterized by several attributes. Which set aligns with the material’s description?
Load type, color, and cost
Support manner, profile (shape of cross-section), length, and material
Installation date, contractor, and finish
Number of bolts, weld type, and paint system
Which statement best describes a simply supported beam?
It is fixed at one end and free at the other.
It is supported at both ends, one by a hinge and the other by a roller, allowing horizontal movement.
It uses more than two supports along its length.
It is only supported by rollers between the ends.
In a continuous beam, what distinguishes it from a simply supported beam?
It has no supports at the ends.
It uses more than two supports, with intermediate supports between the ends.
It always has an overhanging portion beyond the end supports.
It is only suitable for short spans.
Which combination of supports is typical at the ends of both simply supported and continuous beams in this context?
Two fixed supports
One hinged support at one end and one roller support at the other
Two roller supports only

Which statement best describes a cantilever beam as shown, with one end embedded in a wall and the other end extending outward?
A structural member fixed at one end and free at the other, carrying load over its span with shear stress and bending moment
