Question

Calculate the mass (in metric tons) of a blade made of glass fiber reinforced polymers, M_{blade}^{GFRP}M blade GFRP ​ , setting the stress limit equal to fatigue limit of the material \sigma_0^{GFRP} = 180MPaσ 0 GFRP ​ =180MPa.​

Answer 1

Thus we need the mas in tons that is M / 1000

Step-by-step explanation:

• (1) Now 1st we will calculate this:
• Ao ^flap =  81 x 8 π σo^ flap x ho^ flap x ρ(air) x V  x r^2 x L^3
• σo^ flap = 150 x 10^6
• (2) Then we will calculate:
• Ao^edge and σo^edge=150*10^6
• (3) The third step:
• M = 2 x (Ao^flap + Ao^edge) x 86 x 2700
• Finally

• M / 1000

Thus we need the mas in tons that is M / 1000

Answer 2

Your answer is M/1000
