The propeller of an aircraft with a radius of 1.5 m rotates during landing with a frequency of 2000 min ^ -1. determine the speed of the point at the end of the propeller.
Task data: R (radius of the aircraft propeller) = 1.5 m; ν (propeller speed during landing) = 2000 min-1 (in SI system ν = 33.3 Hz).
To determine the speed of the points at the end of the propeller, apply the formula: V = 2 * Π * R * ν.
Calculation: V = 2 * 3.14 * 1.5 * 33.3 = 314 m / s.
Answer: The points at the end of the propeller had a linear speed of 314 m / s during landing.
