Question 43
Open questionCE-2NAT2 marksNeeds review
A 2 m long, axially loaded mild steel rod of 8 mm diameter exhibits the load-displacement (
-
) behavior as shown in the figure. 
Assume the yield stress of steel as 250 MPa. The complementary strain energy (in N-mm) stored in the bar up to its linear elastic behavior will be

Consider a square-shaped area ABCD on the ground with its centre at M as shown in the figure. Four concentrated vertical loads of
kN are applied on this area, one at each corner. 
The vertical stress increment (in kPa, up to one decimal place) due to these loads according to the Boussinesq’s equation, at a point 5 m right below M, is

The figure shows a U-tube having a 5 mm × 5 mm square cross-section filled with mercury (specific gravity = 13.6) up to a height of 20 cm in each limb (open to the atmosphere).
If 5 cm
of water is added to the right limb, the new height (in cm, up to two decimal places) of mercury in the LEFT limb will beLog in to check the answer
