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?
