A. The proeutectoid phase is Fe₃c because 0.95 wt/c is greater than the eutectoid composition which is 0.76 wt/c
b. We determine how much total territe and cementite form, we apply the lever rule expressions yields.
Wx = (fe₃c-co/cfe₃ c-cx = 6.70- 0.95/6.70- 0.022 = 0.86
The total cementite
Wfe₃C = 10-Cx/ Cfe₃c -Cx = 0.95 - 0.022/6.70 - 0.022 = 0.14
The total cementite which is formed is
(0.14) × (3.5kg) = 0.49kg
c. We calculate the pearule and the procutectoid phase which cementite form the equation
Ci = 0.95 wt/c
Wp = 6.70 -ci/6.70 - 0.76 = 6.70 -0.95/6.70 - 0.76 = 0.97
0.97 corresponds to mass.
W fe₃ C¹ = Ci - 0.76/5.94 = 0.03
∴ It is equivalent to
(0.03) × (3.5) = 0.11kg of total of 3.5kg mass.
Electronic balance for the mass.
Measuring cylinder with water to find the volume of the keys (put keys in the cylinder and see the change in volume)
Let the forces on two pillars are N1 and N2
so we will have force balance equation as
also by torque balance we will have
![N_2\times L = 40000 ]times \frac{L}{2} + 19600 \times 8](https://tex.z-dn.net/?f=N_2%5Ctimes%20L%20%3D%2040000%20%5Dtimes%20%5Cfrac%7BL%7D%7B2%7D%20%2B%2019600%20%5Ctimes%208)
here we know that
L = 20 m
Helium and nitrogen because they are both from the noble gas group.
The suns energy is probably produced by <u>nuclear fusion</u>
i hope i helped
