Beam - Visual Dictionary

Question 1

An external moment tending to cause part

of a structure to rotate or bend.

Answer 1

Bending moment

Question 2

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

Answer 2

Resisting Moment

Question 3

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

Answer 3

Camber

Question 4

-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.

Answer 4

Transverse shear

Question 5

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.

Answer 5

Bending Stress

Question 6

A rigid structural member

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

Answer 6

Beam

Question 7

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

Answer 7

Lateral Buckling

Question 8

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

Answer 8

Simple Beam

Question 9

a projecting beam supported at only one fixed end

Answer 9

Cantilever Beam

Question 10

A simple beam extending beyond one its

supports.

Answer 10

Overhanging beam

Question 11

a simple beam extending beyond both if its supports

Answer 11

Double overhanging beam

Question 12

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

Answer 12

Fixed end Beam

Question 13

a beam extending over more than two supports

Answer 13

Continuous Beam

Question 14

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

Answer 14

Haunch

Question 15

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

Answer 15

Suspended span

Hung span

Question 16

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

Answer 16

Cantilever
