Which of the following is NOT true about Planetary gear trains?

Which of the following is NOT true about Planetary gear trains? Correct Answer They are a one-degree-of-freedom systems.

Concept:

Planetary gear trains:

  • Planetary gears are at the heart of modern engineering and are used in gearboxes that power everything from basic plant machinery to cutting-edge electric vehicles. The simple configuration of a central drive and orbiting gears was developed thousands of years ago to model the movements of the planets.
  • Today, engineers use planetary gears in applications that demand high torque density, operational efficiency, and durability. In this article, we explore the principles of operation, how planetary gears work, and where you might find them.
  • The main component of planetary gears are:
    • ​The sun gear that sits in the center (central gear).
    • Multiple planet gears.
    • The ring gear (outer gear).

Additional InformationDegree of freedom:

  • The degree of freedom is defined as the minimum number of independent variables required to define the position or motion of a system is known as the degree of freedom.
  • The degree of freedom is the property of the kinematic chain which shows that in how many directions the connected links of the kinematic can move freely.
  • DOF = 3 (n - 1) - 2l - h

where, n = number of links, l = number of lower pair, h = number of higher pair

R. Maglev is the shortened form of magnetic levitation. S. These trains are called maglev trains. 6. This lack of friction and the aerodynamic design of these trains allow them to reach speeds of over 500 kilometers per hour.
Due to the technical snag in the signal system two trains start approaching each other on the same track from two different stations, 240 km away each other. When the train starts a bird also starts moving to and fro between the two trains at 60 kmph touching each train each time. The bird initially sitting on the top of the engine of one of the trains and it moves so till these trains collide. If these trains collide one and half hour after start, then how many kilometers bird travels till the time of collision of trains?
