EPSON 16) (15 points) Consider a helicopter rotor blade as three long thin rods as shown...
Let us treat a helicopter rotor blade as a long thin rod, as shown in the figure. (Figure 1) . If each of the three rotor helicopter blades is 3.75 m long and has a mass of 135 kg, calculate the moment of inertia of the three rotor blades about the axis of rotation. b- How much torque must the motor apply to bring the blades from rest up to a speed of 5.9 rev/s in 10 s ?
A.) If each of the three rotor helicopter blades is 3.75 m long and has a mass of 135 kg, calculate the moment of inertia of the three rotor blades about the axis of rotation. B.)How much torque must the motor apply to bring the blades from rest up to a speed of 4.1 rev/s in 7.6s ? If each of the three rotor helicopter blades is 3.75 m long and has a mass of 135 kg, calculate the moment of...
The tail rotor section of a Black Hawk helicopter shown in the image consists of four blades, each has a mass of 2 [kg], and a gear box that weights 38 [kg]. The center of gravity of each blade is 0.4 [m] from the rotational axis. The tail section is connected to the main body of the helicopter by an elastic structure. The natural frequency of the tail section is observed as 135 [rad/s). During flight, the rotor operates at...
5. The three rotor blades of a wind turbine can be considered to be long thin rods. Each of the rotor blades is 43 m long and has a mass of 60 Mg. The turbine is spinning at 20 rpm and is generating 2.8 MW of power. This problem DOES need to be written out for your portfolio.

3. Three masses are connected by thin rigid rods as shown below, and are initially at rest on the top of a horizontal table. A circular blob of clay (velocity shown immediately before the collision) hits and sticks to one of the masses as shown. The mass of the rod can be neglected and the object is NOT pinned down to the table 3 m 20 m/s i 40 2 kg Calculate the linear velocity of the center of mass,...
Die to your knowledge of physics and interest in transportation, you have obtained a summer job at the US company Sikorsky, they are interested in investigating the energetic consumption of your new three-rotor helicopter (Sikorsky S97 Raider). The blade of a rotor can be considered as a thin rod. If each of the three blades of the rotor of the helicopter is 3.75m long and has a mass of 135kg, A) Determine the energy needed to operate the rotors (2)...
Solve the following approaches: Due to your knowledge of physics and interest in transportation, you have obtained a summer job at the United States company Sikorsky, they are interested in investigating the energy consumption of your new helicopter three rotors (Sikorsky S-97 Raider). The blade of a rotor can affect like a thin rod. If each of the three blades of the helicopter rotor is 3.75 m long and has a mass of 135 kg, a) Determine the energy needed...
i need only final answer not full solution. send me asap 16. | Two identical cars, #1 g with 20 m/s and #2 moving with 40 m/s, slam on the brakes at the same time [same braking #1 stops after 3 seconds. #2 still moves after 3 sec with how much of its original momentum?

Work out the highlighted questions (3-6) clearly and with units, please. Thanks! 4/5 a the minimum kinetic energy at the apping point? (C) Use conservation of energy to determine the minimum angular velocity of the block just after the collision, (d) then use conservation of angular momentum during the collision to find the initial speed of the bullet vo. (Hint: Ignore the mass of the bullet after the collision. The moment of inertia of the cube about its bottom-right edge...
These questions concern a space station, consisting of a long thin uniform rod of mass 4.3 x 10^6 kg and length 769 meters, with two identical uniform hollow spheres, each of mass 1.7 x 10^6 kg and radius 218 meters, attached at the ends of the rod, as shown below. Please note that none of the diagrams shown is drawn to scale. A. Suppose that the station starts out at rest (not rotating). What we want is to get it...
