A wedge deflects a stream at \( M_1 = 2 \) through \( 20 \) degrees, producing an attached weak oblique shock at \( \beta = 53.4 \) degrees. The normal component Mach number is nearest to
Answer: A
The normal component is \( M_1 \sin\beta = 2 \times \sin 53.4^\circ = 2 \times 0.803 = 1.606 \). Because this exceeds one, the shock is a genuine compression; had the geometry given a normal component below one, no shock could have existed there at all.
