Correct option is C
Given, Rectangular cross-section
B = 4 m , D = 2 m
MIDDLE THIRD RULE FOR RECTANGULAR SECTIONS
[i.e., KERNEL OF SECTION]
Size of rhombus- Central core of a rectangular cross-section is a rhombus with b/3 and h/3 diagonals
Size of rhombus
B = 4/3= 1.33
D = 2/3 = 0.66
So, The point load shall be applied within the rhombus located at centre with diagonals size 1.33 mx0.66m to ensure no tensile stresses developed in column cross section Value of e for no tensile stress along width
