A gyroscope, not to be confused with gyrocompass, is a spinning wheel mounted on gimbal so that the wheel's axis is free to orient itself in any way. When it is spun up to speed with its axis pointing in some direction, due to the law of conservation of angular momentum, such a wheel will normally maintain its original orientation to a fixed point in outer space (not to a fixed point on Earth).

Whirling of shafts occurs due to rotational imbalance of a shaft, even in the absence of external loads, which causes resonance to occur at certain speeds, known as critical speeds.
The relevance of this project is to determine the effect of gyroscopic reaction on bearings. We determine the reactions on bearing due to different spinning angular velocity of rotor and at different precision angular velocity of the system . This concept is useful in selection of bearing during particular application where extra load due to gyroscopic effect occurs on any system.

EE5317: Gyroscopes
Gyros are devices which rely on inertial measurements to measure changes in the orientation of an object. When gyros are combined with accelerometers, all the parameters necessary to determine the position and orientation of an object are available. A combined unit called an “Inertial Measurement Unit” is a common component of aircraft, missiles and other valuable objects whose trajectory needs to be determined by indirect means.
A device consisting of a wheel or disc mounted so that it can spin rapidly about an axis which is itself free to alter in direction. The orientation of the axis is not affected by tilting of the mounting, so gyroscopes can be used to provide stability or maintain a reference direction in navigation systems, automatic pilots, and stabilizers.

HEAP SORT ILLUSTRATED WITH HEAPIFY, BUILD HEAP FOR DYNAMIC ARRAYS.
Heap sort is a comparison-based sorting technique based on Binary Heap data structure. It is similar to the selection sort where we first find the minimum element and place the minimum element at the beginning. Repeat the same process for the remaining elements.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

3. A gyroscope is a device for measuring or maintaining orientation,
based on the principles of angular momentum
Mechanical gyroscopes typically comprise a spinning wheel or disc in
which the axle is free to assume any orientation. This orientation changes
in response to an external torque and due to large angular momentum
associated with the disc's high rate of spin and moment of inertia
4. A conventional gyroscope is a
mechanism comprising a rotor
journaled to spin about one axis,
the journals of the rotor being
mounted in an inner gimbal or
ring; the inner gimbal is
journaled for oscillation in an
outer gimbal for a total of two
gimbals.
The outer gimbal or ring, which is
the gyroscope frame, is mounted
so as to pivot about an axis in its
own plane determined by the
support.
Inner gimbalis mounted in the
gyroscope frame (outer gimbal)
so as to pivot about an axis in its
own plane that is always
perpendicular to the pivotal axis
of the gyroscope frame (outer
gimbal).

6. Gyroscope mainly function on basis of two
properties
1) Rigidity in space: the gyro has a tendency to
resist forces applied to it, it is stable on the axis it
spins. This is the principle behind which a
spinning top stays upright, and the incorporation
of gyroscopes in flight instrument have resulted in
instruments like the artificial horizon which by
maintaining rigidity in space allow for flight solely
by reference to the instruments.
2) Precession: when a force is applied
perpendicular to a spinning rotor the rotor will
resist the force where it is applied and the force
will manifest 90 degrees later in the direction the
rotor is spinning.
.
7. Torque-induced precession (gyroscopic precession) is the phenomenon in which
the axis of a spinning object (e.g., a part of a gyroscope) "wobbles" when a torque is
applied to it, which causes a distribution of force around the acted axis. The
phenomenon is commonly seen in a spinning toy top, but all rotating objects can
undergo precession. If the speed of the rotation and the magnitude of the torque are
constant, the axis will describe a cone, its movement at any instant being atright
angles to the direction of the torque. In the case of a toy top, its weight is acting
downwards from its centre of mass and the normal force (reaction) of the ground
pushing up on it at the point of contact with the support constitute two opposite and
equal forces producing a torque.
8. Fundamental equation describing precession is
τ
where and L are torque and angular momentum
It follows that torque is perpendicular to axis of rotation and perpendicular to L resulting in
motion perpendicular to both L and T.
This is called PRECESSION
Thus if gyroscope spin slows down, its angular momentum decreases and so precession
increases. This continues until
device is unable to rotate fast enough to support its own weight, when it stops and fall off
its support mostly due to friction because friction against precession cause another
precession that goes to cause the fall.
