By using unit conversion, the energy released in kilocalories is 9.42 kcal.
We need to know about unit conversion to solve this problem. There are several energy units which able to explain how much the energy is such as calories and joule. The energy unit can be converted to another unit by unit conversion. The unit conversion of calorie to joule is
1 cal = 4.184 joule
From the question above, we know that
E = 39.4 kJ
By using the unit conversion, we can convert the energy into calorie
E = 39.4 kJ
E = 39.4 x 10³ J
E = 39.4 x 10³ / 4.184 cal
E = 9.42 x 10³ cal
E = 9.42 x 10³ /10³ kcal
E = 9.42 kcal
Hence, the energy released in kilocalories is 9.42 kcal.

Answer:
The resultant strain in the aluminum specimen is 
Explanation:
Given that,
Dimension of specimen of aluminium, 9.5 mm × 12.9 mm
Area of cross section of aluminium specimen,

Tension acting on object, T = 35000 N
The elastic modulus for aluminum is,
The stress acting on material is proportional to the strain. Its formula is given by :

is the stress

Thus, The resultant strain in the aluminum specimen is
