Using the Maslen method find the change in the shock angle at the nose of a cone pitching with about its nose with a small amplitude. Use body attached coordinate system as done in Example 7.1.

Example 7.1

The surface equation of a body is given by \(\mathrm{z}=\mathrm{a}(\mathrm{x} / l)^{1 / 2,} 0 \leq x \leq l\). If this body pitches by \(\alpha=\bar{\alpha} \sin \omega t\) about its nose in small amplitudes, find the surface pressure variation with time.
