Transcript of a projecting beam or member supported at only one end

THE CANTILEVER
What is it?
A CANTILEVER IS A LONG PROJECTING BEAM OR GIRDER FIXED AT ONLY ONE END, USED CHIEFLY IN BRIDGE CONSTRUCTION.
PARTS
FOR SOMETHING TO BE CLASSIFIED AS A CANTILEVER IT NEEDS TO HAVE A BEAM SUPPORTED AT ONE END AND CARRYING A LOAD AT THE OTHER END OR DISTRIBUTED ALONG THE UNSUPPORTED PORTION.
THE IMPROVEMENTS THAT HAVE BEEN MADE TO THE CANTILEVER
BECAUSE ONLY ONE END OF THE BEAM IS SUPPORTED, A CANTILEVER IS TYPICALLY SUBJECTED TO A GREAT DEAL OF STRESS. IF it can't handle all of the stress,A CANTILEVER MAY BREAK. MANY ENGINEERS AND ARCHITECTS HAVE WORKED TO DESIGN BEAMS AND BALANCE LOADS IN A WAY THAT THEY WILL NOT SUFER FROM SUCH STRUCTURAL ISSUES.

HOW THE DIFFERENT TYPES OF CANTILEVERS ARE THE SAME
A RIGID STRUCTURAL MEMBER PROJECTING FROM A VERTICLE SUPPORT, ESPECIALLY ONE IN WHICH THE PROJECTION IS GREAT IN RELATION TO THE DEPTH, SO THAT THE UPPER PART IS IN TENSION AND THE LOWER PART IN COMPRESSION.
