Q1: To keep the intensity of bearing pressure between the column base and concrete compressive and to vary from zero to , the ratio of the moment M to the axial load P should be

ANS:E - <img src="/_files/images/civil-engineering/steel-structure-design/100-14-92-5.png">

As bearing stress variation is triangular avg stress=(2p/BL)÷2 (here it is not mentioned about what is L and what is B so I assumed that L =depth and B=width of section) and frob bending stress formula calculate another stress and compare both the stress you will get the answer.
