R = 7.854 x 10⁵ anpert turns / Wb
Relative permeability = 405.3
Explanation:
Detailed explanation is given in the attached document.
The formula for true strain after derivation from basic terms is; ε_t = In(1 + ε_e)
<h3>How to derive the expression for True Strain?</h3>
Formula for Engineering Stress is;
σ_e = Load/Area
Formula for true stress is;
σ_t = Force/Instantaneous Area
Formula for Engineering Strain is;
ε_e = ΔL/L₀
Formula for true strain is;
dε_t = dL/L
Total true strain is gotten from;
ε_t = ∫(dL/L) between boundaries of L_f and L_o
When we integrate between those boundaries, we have;
ε_t = In[(L₀ + ΔL)/L₀
⇒ ε_t = In[(1+ ΔL/L₀)
⇒ ε_t = In(1 + ε_e)

Answer:Mechanical Engineers
Explanation: Mechanical engineering is an engineering branch that combines engineering physics and mathematics principles with materials science to design, analyze, manufacture, and maintain mechanical systems. It is one of the oldest and broadest of the engineering branches.
