Uniformly Varying Load:

A load that is spread over a beam in such a manner that its extent varies uniformly on each of unit length is called as uniformly varying load. Sometimes, the load is zero at one of the end and enhance uniformly to the other end. Such a load is called as triangular load.

A beam might carry anyone of the above load systems or a combination of two or more systems at a time. Loads might be static or dynamic. Static loads are those which are applied slowly and do not change their magnitude, point or direction of application along time. Dynamic loads are those that vary in time along speed.
