SFD and BMD Analysis of beam Problem for UVL Load by command Method in Ansys FEA

Uniformly Varying Load:

A load that is spread over a beam in such a manner that the rate of loading uniformly varies from point to point along the beam. The load is zero at one end and increases uniformly to the other end. It is also called das triangular load.

Note:

For solving problems on this, the total load is assumed to be acting at a distance of 2/3 of the total length of the load from the zero ends (in fig left end) or 1/3 of the total length of the load from the maximum load end (in fig right end).

Shear Force:
shear force (SF) at a cross-section is the algebraic sum of the forces acting on one side of the section or the other. The sum of those forces to the left of XX axis is numerically equal but in opposite direction to the sum of those to the right. Since the resultant force acting on a beam must be zero. Shear force may also be defined as the unbalanced vertical force to the right or left side of the section.

Bending Moment (M)

Bending Moment (M) at a cross-section is defined as the algebraic sum of the moments of all the forces acting on any one side of that section. The moment obtained by the forces on the left of the beam will be numerically equal an opposite to the right of the beam.
