Answer:
The whole angle is 180 degrees. 180-28 is 152. 152-2 is 150. 150/3 is 50.
So the ratio is 100:60 and that simplified is 5:3. for every 5 blue there is 3 red
a.
b.
The metal obey this law for values of strain until 0.05, where we have a linear relationship (each increase of 0.01 in the strain causes an increase of 100 in the stress). After this point, we don't have a linear relationship anymore.
c. Since an increase of 0.01 in the strain causes an increase of 100 in the stress, the slope is:
Now, calculating the coefficient b (y-intercept), we have:
So the equation is:
d.
The maximum value of stress is 560, and occurs at strain = 0.07.
Answer:
C
Step-by-step explanation:
Because the line is straight and the line is supposed to be going straight up
Answer: b ) 65
Step-by-step explanation:
50 + 65 = 115
115-50 = 65
