Answer:
the critical flaw is subject to detection since this value of ac (16.8 mm) is greater than the 3.0 mm resolution limit.
Explanation:
This problem asks that we determine whether or not a critical flaw in a wide plate is subject to detection given the limit of the flaw detection apparatus (3.0 mm), the value of KIc (98.9 MPa m), the design stress (sy/2 in which s y = 860 MPa), and Y = 1.0.
![ac=1/\pi (\frac{Klc}{Ys} )^{2}\\ ac=1/\pi(\frac{98.9}{(1)(860/2)} )^{2}\\ ac=0.0168m\\ac=16.8mm](https://tex.z-dn.net/?f=ac%3D1%2F%5Cpi%20%28%5Cfrac%7BKlc%7D%7BYs%7D%20%29%5E%7B2%7D%5C%5C%20ac%3D1%2F%5Cpi%28%5Cfrac%7B98.9%7D%7B%281%29%28860%2F2%29%7D%20%29%5E%7B2%7D%5C%5C%20%20ac%3D0.0168m%5C%5Cac%3D16.8mm)
Therefore, the critical flaw is subject to detection since this value of ac (16.8 mm) is greater than the 3.0 mm resolution limit.
Answer:
The moon orbits Earth following a nearly circular path. The same face of the moon always points toward Earth. The moon's orbit is the result of the interaction between the moon's inertia and the gravitational force from Earth.
Answer:
The required radial distance from the center of the toroid is -
<u>r = 4.34 cm</u>
Explanation:
We know that magnetic field inside a solenoid is given by -
B = μni
where 'μ' is the magnetic permeability , 'n' is the number of turns per unit length , 'i' is the current passing through solenoid.
given n = 550 turns/meter
We know that magnetic field inside a toroid is -
B = μ×
×i [Current is same in both the devices] , where 'N' is the total number of turns in the toroid and 'r' is the radial distance from the center of the toroid.
Given N = 150.
Equating the two magnetic fields , we get -
μni = μ×
×i
∴ ![r = \frac{N}{2n\pi }](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7BN%7D%7B2n%5Cpi%20%7D)
Substituting the values we get -
r = 0.0434 m = 4.34 cm
