You are asked to design an airplane propeller to turn at 2400 rpm. The forward air speed of the plane is to be 75 m/s and the speed of the tips of the propeller blades must not exceed 270 m/s. a) What is the maximum radius the propeller can have? b) With this radius, what is the acceleration of the propeller tip?

a) A wind turbine with two or four hollow hemispherical cups connected to a pivot is commonly uscd to measure wind speed. Consider a wind turbine with four 8-cm- diameter cups with a center-to-center distance of 40 cm, as shown in Fig. PI1-35. The pivot is stuck as a result of some malfunction, and the cups stop rotating. For a wind speed of 15 m/s and air density of 1.25 kg/m3, determine the maximum torque this turbine applies on the pivot. A hemisphere at two different orientations for Re > 10 40 cm C04

In the movie Kill Bill the character Gogo Yubari fights with a meteor hammer, which is a bladed metal sphere on the end of a chain. Let’s assume Gogo is spinning the meteor hammer in a vertical spin, as shown below, with a radius of motion as 1 m. She spins the weapon at 18 m/s. Gogo then lets out more chain, increasing the radius to 1.62 m. What is the new velocity of her weapon?

An aircraft performs a maneuver called an aileron roll. During this maneuver, the plane turns like a screw as it maintains a straight flight path, by using its ailerons to set the wings in circular motion. If it takes the plane 35s to complete the circle and each wing length is 4.6m, what is the acceleration of the wing tip? O A. 0.69 mis? OB.0. 15 m/s? OC14 mis? OD.6.7 mis?

You are on a boat in the middle of the Pacific Ocean at the equator traveling in a hydrofoil going at a constant speed of 300 m/s. The water is perfectly still. What is your acceleration: a) If you’re heading due North? b) If you’re heading due East? c) If you’re heading straight up (something probably went wrong at this point). You may assume the following: The earth has a radius of 6371 km. The earth makes one full revolution every 24 hours. The gravitational constant at sea level is 9.81 m/s2. East and North are relative to the Earth’s axial north, not magnetic north.
