Snow load can be an uneven loading
in horizontal roofs.
What is the magnitude and location of
application of this load?
APPLICATIONS
(continued)
Wind loads change with the
height of the floor.
How can we determine the
magnitude and resultant of
wind load?

(continued)
The pressure applied to objects
submerged in fluids increase
with depth.
Assumming that the figure
shows an undergrown door,
how much force is needed to
open it?
PRESSURE DISTRIBUTION OVER A SURFACE
Sometimes we would want to describe distributed loads in terms
of functions.
In the figure above, the pressure applied on the
plate is described by the function p = p(x,y)
The magnitude of the resultant force would be equal to the sum
of all the parallel forces applied on the plate
