symbols have their usual significance
YAK2
YAK2 YAK2 YR2
(a)
2R
(b)
(C)
(d)
R
AR2
R2​

Answer 1

Answer:

a______________________________2R

Answer 2

The correct answer is option (a) 2R.

Explanation:

• The internal bending moment of a beam is given by the 2R expression where the symbols have their usual significance YAK2 YAK2 YAK2 YR2.
• Internal Bending Moment which is represented by M ≡ equal in magnitude but opposite in direction to the algebraic sum of the moments about the section of all external loads and support reactions acting on either side of the section being taken.
• The shearing forces is responsible to produce a vertical shear across transverse sections of the beam.
