A twin-blade aircraft propeller has a mass of 30.0 kg and a radius of 1.50 m. When the aircraft is flying at its top speed of 162 knots the tips of the propeller blades may not move faster than 300 m/s through the air (otherwise they would be travelling supersonically). Determine: 3.1 the maximum safe angular speed of the propeller in rpm; 3.2 the torque the engine must exert on the propeller in order for it to reach this maximum angular speed within 30.0 s of start-up (assuming the angular acceleration remains constant).

An airplane propeller is 1.99 m in length (from tip to tip) with mass 93.0 kg and is rotating at 2500 rpm (rev/min) about an axis through its center. You can model the propeller as a slender rod. What is its rotational kinetic energy? Suppose that, due to weight constraints, you had to reduce the propeller's mass to 75.0% of its original mass, but you still needed to keep the same size and kinetic energy. What would its angular speed...
