3. A bar of steel 24 mm in diameter was subjected to a tensile load of 60 kNs and measured extension on a 20-cm gauge length was 0.009 cm and the change in diameter was 0.00375 cm. Calculate the Bulk modulus?
4. What is the allowable load carrying capacity of a circular column section of 400 mm diameter reinforced with 6x25 mm diameter bars adequately tied with spirals? Consider concrete of grade M25 and steel of grade Fe 415.

Section - A

1. In each group of words given below, show which words (if any) share a common suffix.

2) Look at the following sentence

The President addressed the nation on the eve of the Independence Day.

Any sentence can be split into smaller units (let us call them blocks). For example the above sentence can be split into following major blocks. [The President] [addressed] [the nation] [on the eve] [of the Independence Day]

Split the following sentences in a similar way :

• The boy wearing the blue cap is my brother.
• I met a student of philosophy in the train.
• Lucknow is as hot as Kanpur.
• Meena was reading a book and Rekha was watching Television.
• As it was raining the children played inside the house.

3) Give the missing number in the following sequences :

1. 1, 4, 9, 16, ---, 36
2. 2, 4, 7, 12, 21, ---
3. 6, 9, 14,---, 30, 41
4. 6, 24, ---, 96, 150, 216

(Note : Only those students who have a background in linguistics should attempt this section)
