When a circular rod of diameter 'd' welded to a rigid plate by a circular fillet weld of size 's' is subjected to a twisting moment 'T',then the maximum shear stress is given by

In a beam of length L, four possible influence line diagrams for shear force at a section located at a distance of L/4 from the left end support (marked at P, Q, R and S) are shown below. The correct influence line diagram is

At a certain section of a shaft 80 mm in diameter there is a bending moment of 3.5 kNm and a twisting moment of 5 kNm. If the Poisson’s ratio of material is 0.28 then the magnitude of stress acting alone that can produce the same maximum strain will be

During the subsurface investigations for design of foundations, a standard penetration test was conducted at 4.5m below the ground surface. The record of number of blows is given below.

Assuming the water table at ground level, soil as fine sand and correction factor for overburden as 1.0, the corrected ‘N’ value for the soil would be
