Solution: 
Taking a rectangular weld all around for filet weld area is given as: 
? = 1.414 ℎ (? + ?) 
Here  
h = thickness of the weld size= 0.0598 in, 
 b = thickness of the sheet = 1 in, and  
d = width of the sheet = 7.5 in 
? = 1.414 ? 0.0598 (1 + 7.5) 
? = 0.719 ??2 
Centroid from X-axis: 
�̅� =
?
2
=
1
2
= 0.5 ??
Centroid from Y-axis: 
�̅� =
?
2
=
7.5
2
= 3.75 ?? 
Unit second moment of area is given as: 
?? =
?2
6
(3? + ?) 
?? =
7.52
6
(3 ? 1 + 7.5) 
?? = 98.4 ??
3 
Second moment of area: 
? = 0.707 ? 0.0598 ? 98.4 = 4.16 ??
