The asymmetric roof truss is of the type used when a near normal angle of incidence of sunlight onto the south-facing surface AB
C is desirable for solar energy purposes. The five vertical loads represent the effect of the weights of the truss and supported roofing materials. The 400-N load represents the effect of wind pressure. Determine the equivalent force-couple system at A. The couple is positive if counterclockwise, negative if clockwise. Also, compute the x-intercept of the line of action of the system resultant treated as a single force R.

is the volume of the sample when the water content is 10%.
<u>Explanation:</u>
Given Data:
First has a natural water content of 25% = = 0.25
Shrinkage limit,
We need to determine the volume of the sample when the water content is 10% (0.10). As we know,
------> eq 1
The above equation is at ,
Applying the given values, we get
Shrinkage limit is lowest water content
Applying the given values, we get
Applying the found values in eq 1, we get
