the new jersey barrier is commonly used during highway construction. determine its weight per foot of length if it is made from plain stone concrete

Step 1

We have to find out the weight per foot of length of the new jersey barrier which is commonly used during highway construction.

Following is the figure of new jersey barrier with dimensions:

Step 2

we know that the density of plain stone concrete is = 144 lb/ft^{3}

The section of the barrier is divided into three parts:

Consider following as the first section:

Step 3

Second section is ...
