Technician B is correct because the way aluminum collapses can be predicted.
Hardened steel and aluminum are two metals used for different purposes including:
- Construction.
- Appliances.
- Small utensils.
- Airplanes.
- Vehicles.
These two materials have slightly different features in terms of resistance, flexibility, etc.
In the case of hardened steel, this is considered to be malleable but strong. This means it is possible to change its shape under some conditions but it can resist great forces and pressure. Moreover, if the hardening process is carried out properly all the areas should be equally strong.
On the other hand, aluminum is recognized due to its durability and for being lighter than other materials. Despite this, aluminum is more flexible than steel and collapses under weaker forces. This has been widely studied because aluminum collapse shows a predictable pattern.
Based on this, only technician B is correct.

Answer:
The minimum length of the vertical curve that can be used is 416.63 m
Explanation:
g₁ = -1.2% , g₂ = 0.8%
Station (Sta) = 75 + 00
Elevation (Ele) = 50.90 m
x₀ = Sta(VPC) = Sta(VPI) - L/2 ⇒ 7500 - L/2
y₀ = Ele(VPC) = Ele(VPI) - g₁L/2 == 50.90 - (-0.012)L/2 ⇒ 50.90 + 0.012L/2
at Sta 75+40, x = 7540 -x₀ = 40 + L/2
at Ele, y = 51.10 + C = 51.10 + 0.80 ⇒ y = 51.90 m
Equation of vertical curve is
Substituting the values for x and y
Solving : L = 416.63 m
