Steel part 2 1-50 part 2

A strut is a:

• Wooden tension member

• Steel cable

• Truss compression member

• Purlin brace

A stanchion is used for:

• Temporary support

• Carrying light load

• Heavy built-up columns

• Roofing sheets

The ratio of effective length to least radius of gyration is called:

• Moment of inertia

• Buckling index

• Slenderness ratio

• Bending modulus

Crushing failure occurs mostly in:

• Long slender columns

• Short stocky columns

• Cantilevers

• Welded joints

The tendency of a column to bend even under axial load is called:

• Torsion

• Crushing

• Buckling

• Shear lag

Beams are primarily subjected to:

• Axial loads

• Bending moment and shear

• Only torsion

• Compression

Which beam supports flooring but no other beams?

• Girder

• Lintel

• Joist

• Purlin

Lintel is used:

• In columns

• Over windows and doors

• In RCC footings

• Under trusses

A beam supported by roof trusses is called:

• Lintel

• Girder

• Joist

• Purlin

Compound beams are used when:

• Rolled section suffices

• Flexural strength exceeds requirement

• Rolled section is inadequate

• Shear is zero
