Title:- CURVED BEAMS/CRANE HOOK (SOM-II) In this ppt file I've included all the information about a Beam, what is beam? it's types. But as tha topic is curved beams so curved beams is briefly discussed. Definition, it's type, material, and it's Application and examples. Also some usefull formulas related to curved beams and crane hooks are given with an appropriate example.

7/16/2021 PCTE GROUP OF INSTITUTES
A beam is a structural element that primarily resists loads applied
laterally to the beam's axis. Its mode of deflection is primarily by
bending. The loads applied to the beam result in reaction forces at
the beam's support points.

If a beam is originally curved before applying any bending moment,
then it can be considered curved beam. It's neutral axis no more
coincides with centroidal line. It’s neutral axis is curved without any
applied load or deformation instead of being straight.

TYPES OF CURVED
BEAMS
On the basis of cross section curved beams can be of many types.
For ex.
Square, Rectangular, Circular, Triangular, I-section, H-section, T-
section, Trapezoidal etc.

APPLICATION OF
CURVED BEAMS
A particular case in which this occurs is that where the axis of the
beam is curved. Important practical applications include chain links,
crane hooks, pipe bends and curved segments of machine tool
frames.

Circular cross-section
Curved beam
• Circular type of beam/bar used in making
of Hooks and Rings. These Hooks & Rings
are used in various industries &
machinery

12. 7/16/2021 PCTE GROUP OF INSTITUTES 12
• Rectangular, Square,L, I-section & T-section
curved beams are used mainly in Bridge making,
making of Electric towers, Mobile towers,
Building Houses. Also used in many machinery.
Square, Rectangular, I,L,T-
section Curved beam

TRAPEZOIDAL CURVED
BEAMS
• Curved bars of especially
Trapezoidal section are used to
make Hooks of heavy duty to lift up
heavy loads. Crane Hooks are made
up of Trapezoidal section.

MATERIAL OF CURVED
BEAMS/BARS/HOOKS
Curved Beams/Bars/Hooks are used to resist heavy loads in
Structure like bridge, machines, cranes etc. Material used for
making these type of beams/hooks are Carbon steel, Alloy Steel,
HSLA(High Speed Low Alloy), Gray Cast Iron, Chromium Steel.

15. Assumptions
• Homogeneous and isotropic material
• Linear elastic response
• Uniform cross-sections
• Symmetric with axis of symmetry
perpendicular to applied moment M
• Cross-sections remain plane
• Cross-section distortion in its plane
neglected
