1
Q

An external moment tending to cause part

of a structure to rotate or bend.

A

Bending moment

2
Q

An internal moment equal and opposite to a bending moment generated by a force couple to maintain equilibrium of the section being constructed

A

Resisting Moment

3
Q

a slight convex curvature intentionally built
into a beam, girder or truss to compensate for an anticipated
deflection

A

Camber

4
Q
-An external shear force at a cross section
of a beam or other member subject to
bending, equal to the algebraic sum of
transverse forces on one side of the
section.
A

Transverse shear

5
Q

A combination of compressive and tension stresses developed at. cross section of a
structural member to resist a transverse force. having a maximum value at the surface furthest from the neutral axis.

A

Bending Stress

6
Q

A rigid structural member

designed to carry and transfer transverse loads across space to supporting elements

A

Beam

7
Q

the buckling of a structural member induced by compressive stresses acting on a slender portion insufficiently rigid in the lateral diraction

A

Lateral Buckling

8
Q

A beam resting on simple support at both
ends, which are free to rotate and have no
moment Resistance. As with any statically
determinate structure, the values of all
reactions, shears. and moments for a
simple beam are Independent of Its Cross-sectional shape and material

A

Simple Beam

9
Q

a projecting beam supported at only one fixed end

A

Cantilever Beam

10
Q

A simple beam extending beyond one its

supports.

A

Overhanging beam

11
Q

a simple beam extending beyond both if its supports

A

Double overhanging beam

12
Q

a beam having both ends restrained against translation and rotation. The fixed ends transfer bending stresses, lncrease the
rigidity of the beam. and reduce Its
maxlmum defIect1on

A

Fixed end Beam

13
Q

a beam extending over more than two supports

A

Continuous Beam

14
Q

The part of a beam that is thickened or deepened to develop greater moment resistance

A

Haunch

15
Q

A simple beam supported by the
cantilevers of two adjoining spans with
pinned construction Joints at points of·
zero moment. Also called

A

Suspended span

Hung span

16
Q

a beam or other rigid structural member extending beyond a fulcrum and supported by a balancing member or a downward force behind the fulcrum

A

Cantilever
