Answer:
The answer is " and 157.5 MPa".
 and 157.5 MPa".
Explanation:
In point A:
The strength of its products with both the grain dimension is linked to this problem. This formula also for grain diameter of 310 MPA is represented as its low yield point  

Here y is MPa is low yield point, x is mm grain size, and k becomes proportionality constant.  
Replacing the equation for each condition:  

People can get yo = 275 MPa with both equations and k= 15.5 Mpa  .
.
To substitute the answer,  

In point b:
The equation is 
equation is:

by putting the above value in the formula we get the  value that is= 157.5 MPa
 value that is= 157.5 MPa

Explanation:
This relationship, known as Faraday's law of induction (to distinguish it from his laws of electrolysis), states that the magnitude of the emf induced in a circuit is proportional to the rate of change of the magnetic flux that cuts across the circuit.
