Helicpoter Takeoff

A helicopter with \({{params.n}}\) blades needs to spin its rotor at \({{params.RPM}} \ \rm{RPM}\) to take off. Each blade has a length \({{params.L}} \ \rm{m}\) and a mass of \({{params.m}}\ \rm{kg}\). Assume the mass of the blades is uniformly distributed across its length. The blades are initially stationary.

Part 1

If the rotor exerts a constant moment of \({{params.M}} \ \rm{Nm}\), how much time is needed for the blades to spin fast enough for takeoff?
