Answer: L.M = 34.69
Area of the bar = 25835m^2
Explanation: To design a bar that can withstand temperature at 773K for 10years, we need to calculate and know:
1) the Larson Miller value
2) rupture time
3) creep rate
4) stress and load.

Answer:
the tension produce by the bird in the wire is 610.3 N.
Explanation:
given information:
mass of the bird, m = 1 kg
distance of two telephone pole, L = 50 m
wire sag, y = 0.2
the tension of the wire can be calculate by the following equation
tan θ = y/(L/2)
= 0.2/(50/2)
= 0.2/25
thus
θ = arc tan (0.2/25)
= 0.46°
according to Newton's first law
ΣF = 0, vertical direction
T sin θ + T sin θ - mg = 0
2 T sin θ = m g
T = mg/2 sinθ
= 1 x 9.8/(2 sin 0.46)
= 610.3 N
