First you can plan the speech like when do you say which and what ect.
then you can write it down and present it!
you can include your opinions on freedom and you can ask your family members and friends about their opinions too. in my opinion freedom is letting go of concerns and being happy.
B, because propel is to move forward.

Answer:
1.4
Explanation:
The relative uncertainties known are:
eP = 0.1
eD = 0.03
eσ = 0.16
The equation for the stress is:
σ = P / A
The load in function of the strength and section is:
P = σ * A
P = π/4 * D^2 * σ
Now we add a safety factor:
P / f = π/4 * D^2 * σ
This safety factor will make P smaller.
We think of the worst condition that could happen, which is if the load is greatest and the diameter and strength smallest:
1 + 10% = 1.1
1 - 3% = 0.97
1 - 16% = 0.84
1.1*P / f = π/4 * (0.97*D)^2 * 0.84*σ
We forget about the actual variables and focus only on the numbers that multiply them:
1.1 / f = 0.97^2 * 0.84
1.1 / (0.97^2 * 0.84) = f
f = 1.4
With a factor of safety of 1.4 the largest load wont cause a failure even in the case of the smallest diameter and the smallest material strength.
