13. Concentrated load:
A concentrated load is the one which acts over
so small length that it is assumed to act at a point.
Practically, a point load can not be places as knife
edge contact but for calculation purpose we
consider that load is being transmitted at a point.
Figure represents point loading at points A and B.
14. Uniformly distributed load:
A uniformly distributed load implies a constant
intensity of loading (w). It is generally abbreviated
as U.D.L. and its unit is kN/m. Figure represents
a U.D.L. between points A and B.
15. Uniformly varying load:
A uniformly varying load implies that the intensity
of loading increases or decreases at a constant
rate along the length.
w = w0 = k . x
where k is the rate of change of the loading intensity,
w0 being the loading at the reference point.
