1) The document describes the design and fabrication of an automated motorized mechanical jack. A mechanical jack is commonly used to lift vehicles but requires significant manual effort.
2) The proposed motorized jack replaces the manual turning mechanism with an electric motor powered by a vehicle battery. Gears connect the motor to the screw mechanism to automatically raise and lower the jack.
3) The motorized jack is intended to reduce worker fatigue by automating lifting operations. It allows even unskilled workers to easily lift vehicles for maintenance in small automobile garages.
An automotive jack is a device used to raise all or part of a vehicle into the air in order to facilitate repairs. Most people are familiar with the basic car jack (manually operated) that is still included as standard equipment with most new cars. These days, a car jack is an important tool to have in our vehicle due to unknown upcoming event such as flat tire in our journey. Even so, people who like to rotate their tires themselves or who may install snow tires before the winter and remove them in the spring need to use a jack to perform the job. Changing a flat tire is not a very pleasant experience. Women have a much lighter skeleton that means, among other things, woman can’t pull more forces as well as men and are at greater risk of skeletal injuries. Usually the car purposely tries to get a flat tire at the least opportune moments.

Introduced gearless power transmission arrangement used for skew shafts. In this transmission system no. of pins or links used must be odd..3,5,7,9…..& centers of any two pins or links hole must not be on that line which represent the diameter of the shaft. If more pins or links used motion will be smoother, but increase in no. of pins or links not at the cost of strength of the shaft. Pins or links are fixed (may be permanent of temporary) in the drilled holes at the both shaft ends due to which motion is transferred. The dimensions of the pins or links and angle for the pins are all given very precisely, holes drilled very accurately.
Proposed arrangement used for skew shafts at any angle & if there is a need we can change the angle between shafts during motion or during intermittent motion with any profile of shafts having rotational motion along its own axis. The Working of this arrangement is very smooth & use very effectively with a very minimum amount of power losses.

Development and Performance of Electro Hydraulic ExcavatorYogeshIJTSRD
The heavy earth moving machineries HEMM like hydraulic excavators play a major role in the construction and mining industries. In an industry of mining and construction, a hydraulic excavator plays a major role in action to perform a carry an heavy load. Employing the technology of automation, an alternative solution is made to replace the manual operation. By addressing the concept of automation in construction, the inevitable usage of embedded is accumulated to introduce in earthmovers. In a mass production or construction site, unplanned work would lead to time consuming and fault. To overcome the major disadvantage of time consuming, so implementation of automation is made on excavators. This could be made workers do other work sequentially with half monitoring the working process of excavator. This also favors the firm or industry to increase the work capability with an adequate number of laborers. K. S Mohan Raj | A Arun Negemiya | C Sangeevi "Development and Performance of Electro-Hydraulic Excavator" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-5 | Issue-5 , August 2021, URL: https://www.ijtsrd.com/papers/ijtsrd44966.pdf Paper URL: https://www.ijtsrd.com/engineering/mechanical-engineering/44966/development-and-performance-of-electrohydraulic-excavator/k-s-mohan-raj
Magnetic Levitating Hover Board to Work as a Forkliftijtsrd
Nowadays storing or retrieving goods from warehouses etc. there is use forklifts extensively. They play a vital role in reducing manual labor to a great extent. It has one shortcoming in the fact that it cannot access small spaces. There is also need skilled personal to operate the vehicle. Apart from these things forklifts also get damaged due to lack of maintenance. The main objective of this magnetic levitating hover board is to access all kinds of spaces inside the workshops and further reduce human effort by using magnetic levitation principle to create a lift to assist in hovering of goods over a copper surface. Hover board is built, which makes it easy to move around heavy objects inside the workshop with minimal effort and more efficiently decreasing the time consumed in the whole process. Electronic speed controller is used to control the rpm of motor which is used to rotate the discs that contain the N52 magnets.

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.
