5X = Y12 ???? If so...., Y12 = 5X Y = 12th root(5X) ===============
The only difference between Y12 and T12 is the Kilos per meter. In a Y12 there is 0.888 Kilos and a T12 bar has 0.612 Kilos.
12mm
785okg/m3
If this is an equation you left out the equal sign. Do you mean y8=y12-4. If so add 4 to both sides. You have 4+y8=y12. Then substract y8 from both sides. You have 4=y4. Divide both sides by 4. You have y=1.
0.887 kg per m
It is a deformed round steel bar and has a diameter of 12mm.
-5 plus 0 is -5. That is true whatever the value of y.
170 Y12 Bar to the ton at 6000 M long
y2x - just double the coordinate of y to get x. xy12 - i have no idea
hardenhuish is a school with 6 different years, y7, y8, y9, y10, y11 and the 6 forms y12 and y13.
y-parameters :- I1=Y11V1 + Y12V2 I2=Y21V1 + Y22V2 so to obtain Y11 and Y21 make V2=0 , (shorting the output terminals) Y11=I1/V1 Y21=I2/V1 so to obtain Y12 and Y22 make V1=0 , (shorting the input terminals) Y12=I1/V2 Y22=I2/V2 as all the admittance parameters obtained are due to either shorting the input or shorting the output terminals so we ca;; these parameters as short circuit admittance parameters
