Answer:
(a) the subtransient current through the breaker in per-unit and in kA rms = 71316.39kA
(b) the rms asymmetrical fault current the breaker interrupts, assuming maximum dc offset. = 152KA
Explanation:

The load is 17156 N.
<u>Explanation:</u>
First compute the flexural strength from:
σ = FL / π
= 3000 
(40 10^-3) / π (5 10^-3)^3
σ = 305 10^6 N / m^2.
We can now determine the load using:
F = 2σd^3 / 3L
= 2(305 10^6) (15 10^-3)^3 / 3(40 10^-3)
F = 17156 N.
