critical mach number in a sentence

Examples

2. :I understand the crack of a whip can cause the tip of the whip to reach a critical Mach number.
3. The Supermarine Spitfire's much thinner wing gave it a considerably higher critical Mach number ( about 0.89 ).
4. Their critical Mach numbers are higher than those of subsonic and transonic aircraft, but are still less than Mach 1.0.
5. Similarly, the specific altitudes at which the stall speed meets the critical Mach number will differ depending on the actual atmospheric temperature.
