Answer:
given d= 10.2x10-3m
change in diameter d' =3.4x10-6 m
elastic modulus=207x109pa
1/m=0.30
we know that stress/strain=E
but poissons ratio 1/m = lateral starin/longitudinal starin
0.3= (d'/d)/(L'/L)
L'/L = 3.4x10-6/(0.3x10.2x10-3)
= 1.11*10-3
E= (f/A)/(L'/L)
force f= E*A*(L'/L)
f =(1.11*10-3)*207*109*(3.1415*(10.2*10-3)2)/4
= 18775.2N =18.775KN
Explanation:
The force that produce an elastic reduction is 18.775KN

Answer:
6.99 x 10⁻³ m³ / s
Explanation:
Th e pressure difference at the two ends of the delivery pipe due to atmospheric pressure and water column will cause flow of water.
h = difference in the height of water column at two ends of delivery pipe
6 - 1 = 5 m
Velocity of flow of water
v = √2gh
= √ (2 x 9.8 x 5)
= 9.9 m /s
Volume of water flowing per unit time
velocity x cross sectional area
= 9.9 x 3.14 x .015²
= 6.99 x 10⁻³ m³ / s
Answer:
Part a: The yield moment is 400 k.in.
Part b: The strain is 
Part c: The plastic moment is 600 ksi.
Explanation:
Part a:
As per bending equation

Here
- M is the moment which is to be calculated
- I is the moment of inertia given as

Here
- b is the breath given as 0.75"
- d is the depth which is given as 8"



The yield moment is 400 k.in.
Part b:
The strain is given as

The stress at the station 2" down from the top is estimated by ratio of triangles as

Now the steel has the elastic modulus of E=29000 ksi

So the strain is 
Part c:
For a rectangular shape the shape factor is given as 1.5.
Now the plastic moment is given as

The plastic moment is 600 ksi.
