Force in the normal(perpendicular) direction = PCos0.
Area in inclined say A'.
Then A = A'Cos0, A' = A/cos0.
stress = force/area.
Pcos0/A/cos0.
pcos^20/A.
Area in inclined say A'.
Then A = A'Cos0, A' = A/cos0.
stress = force/area.
Pcos0/A/cos0.
pcos^20/A.

Pθ = (P/2) + (P/2)cos2θ,
Pθ = P/2 (1+cos2θ),
Pθ = P/2 (2cos^2(θ)),
Therefore, Pθ = P/2 cos^2(θ).
Pθ = P/2 (1+cos2θ),
Pθ = P/2 (2cos^2(θ)),
Therefore, Pθ = P/2 cos^2(θ).
