Answer:
The answer is " 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
