Technician A is wrong.
- Usually, hoods have what is called "Crush Zones" underneath the panels. The function of the Crush Zone is to prevent the hoods, during a collision, from entering into the passenger space.
- The crush zones allow the hoods to fold instead.
Technician B is right.
- Automobile producers now make use of a hybrid form of hood that consists of fiberglass reinforced with plastic.
- They are mostly used for trucks that have a low volume of production.
- The hood is built using a process called Resin Transfer Model (RTM).

C because i know what i’m taking about
Answer:
A) Upper bound modulus of elasticity; E = 165.6 GPa
B) Lower bound modulus of elasticity; E = 83.09 GPa
Explanation:
A) Formula for upper bound modulus is given as;
E = E_m(1 - V_f) + E_f•V_f
We are given;
E_m = 60 GPa
E_f = 380 GPa
V_f = 33% = 0.33
Thus,
E = 60(1 - 0.33) + 380(0.33)
E = (60 x 0.67) + 125.4
E = 165.6 GPa
B) Formula for lower bound modulus is given as;
E = 1/[(V_f/E_f) + ((1 – V_f)/E_m)]
E = 1/[(0.33/380) + ((1 – 0.33)/60)]
E = 1/(0.0008684 + 0.01116667)
E = 1/0.01203507
E = 83.09 GPa
