3. 2 Load

i) Loads
This load acting on an area that is too small and can be  said to act at one point as the point x (Figure 3.6). unit = N



ii) A uniformly distributed load
It acts on the whole or part of a long beam with a uniform   way (figure 3.7). units = N / m

 


iii) Non-uniform distributed load
This load is continually changing. Normally the load form a  triangle (Figure3.8). units = N / m


iv) The moment of the coupling
It is the effect of a twisting action imposed on a beam (clockwise direction) will be produced by two forces F acting on the arm. The value of M1 is (F x d) Nm. While  M2 is another example of the coupling moments acting   at point x, in an anticlockwise direction
