Answer:
The original length of the specimen
Explanation:
Original diameter = 30 mm
Final diameter = 30.04 mm
Change in diameter Δd = 0.04 mm
Final length = 105.20 mm
Elastic modulus E = 65.5 G pa = 65.5 × M pa
Shear modulus G = 25.4 G pa = 25.4 × M pa
We know that the relation between the shear modulus & elastic modulus is given by
This is the value of possion's ratio.
We know that the possion's ratio is given by
0.00476
Final length = 105.2 m
Original length
This is the original length of the specimen.
Answer:
The expression is shown in the explanation below:
Explanation:
Thinking process:
Let the time period of a simple pendulum be given by the expression:
Let the fundamental units be mass= M, time = t, length = L
Then the equation will be in the form
where k is the constant of proportionality.
Now putting the dimensional formula:
Equating the powers gives:
a = 0
b + c = 0
2c = 1, c = -1/2
b = 1/2
so;
a = 0 , b = 1/2 , c = -1/2
Therefore:
T =
where k =
