## Homework Statement

Number 1-5 from here http://www.slideshare.net/hotman1991/met-302-chapter-01

How do I deal with the 1.5 kip/ft? Am I right to think that the smaller arrows to the left mean that the kip/ft there is less than 1.5kip/ft? How can I find kip/ft at a given point along the horizontal axis?

* I know that the answers are given, however I do not understand it.

## Homework Equations

Possibly A = 1/2(b*h) = 1/2(12)(1.5) = 9 kips

EDIT: I also found the same 9kip/ft through ∫(1.5x/12)dx from 0 to 12.

## The Attempt at a Solution

The answers use area to get total (?) kips. I sort of understand why they would do that, something like integrating from 0-12 ft. However, I do not understand how they found 9kips at 4ft from B, or why they put the 9 kips there at 4ft.
