The engine of an aircraft propeller delivers an amount of power 173 hp to the propeller at a rotational velocity of 2430 rev/min. How much torque does the aircraft engine provide? How much work does the engine do in one revolution of the propeller?
A propeller is rotating about an axis perpendicular to itscenter,as the drawing shows. The axis is parallel to the ground. Anarrowis fired at the propeller, travels parallel to the axis, andpassesthrough one of the open spaces between the propeller blades.Theangular open spaces between the three propeller blades areeachÏ/3 rad (60.0°). The vertical drop of thearrow may beignored. What is a maximumvalue Ï for the angular speed ofthepropeller, beyond which the arrow cannot pass through an openspacewithout being struck by one of the blades. Find this maximumvaluewhen the arrow has length L andspeed v shownin the following table.
