2. • Shear Force - The algebraic sum of the all forces either left hand side either
right hand side is called the shear force
• Bending Moment- The algebraic sum of the all moment either left hand side
either right hand side is called Bending moment

3. . A structural member which is
long when compared with its
lateral dimension , subjected to
tranverse forces so applied as to
induce bending of the member in
an axial plane , is called a beam.

4. • Types of load on beam
• concentrated or point load
• uniformly distributed load
• uniforming varying load
• concentrated moment

5. • positive direction are denoted by an internal shear forces that cause
clockwise rotation of the member on which it acts, and an internal
moment that cause compression , or pushing on the upper arm of the
member.
• loads that are opposite to these are considered negative.
