It provides examples and diagrams of displacement, velocity, and acceleration for each type. It also discusses cam profiles, including an example problem to construct the profile of a cam with specified motion parameters. The next lecture topic will be on belts, ropes and chains. Students are provided the lecturer's contact information.
A cam is a rotating machine element which gives reciprocating or oscillating motion to another element known as the follower.Though the cams may be classified in many ways, among them we can classify:
1. Radial or disc cam.
2. Cylindrical cam.

Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
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.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
5. a) Uniform motion (constant velocity)
Displacement diagram: Displacement is the distance that
a follower moves during one complete revolution (or
cycle) of the cam while the follower is in contact with the
cam.
It is the plot of linear displacement (s) of follower V/S
angular displacement (θ) of the cam for one full rotation
of the cam.
A period is a part of the cam cycle and it includes the
following:
Rise (Outstroke) – the upward motion of the follower caused
by cam motion.
Fall (Return stroke) – the downward motion of the follower
caused by cam motion.
Dwell – the stationary position of the follower caused by
cam motion.
7. a) Uniform motion (constant velocity)
Displacement diagram
Since the follower moves with uniform velocity during
its rise and fall, the slope of the displacement curve
must be constant as shown in fig

10. b) Simple harmonic motion
Since the follower
moves with a
simple harmonic
motion, therefore
velocity diagram
consists of a sine
curve and the
acceleration
diagram consists of
a cosine curve.

Maximum acceleration of the follower on the
outstroke

12. c) Uniform acceleration and retardation
Since the
acceleration
and
retardation
are uniform,
therefore the
velocity varies
directly with
time.
13. c) Uniform acceleration and retardation
Maximum velocity of follower during outstroke
Maximum velocity of the follower during
return stroke
Maximum acceleration of the follower during
outstroke
Maximum acceleration of the follower during

14. d) Cycloidal motionMaximum velocity of follower during outstroke
Maximum velocity of the follower during

Maximum acceleration of the follower during
outstroke
Maximum acceleration of the follower during

18. Example 20.1. A cam is to give the following motion to a knife-edged
follower :
1. Outstroke during 60° of cam rotation ;
2. Dwell for the next 30° of cam rotation ;
3. Return stroke during next 60° of cam rotation, and
4. Dwell for the remaining 210° of cam rotation.
The stroke of the follower is 40 mm and the minimum radius of the cam
is 50 mm. The follower moves with uniform velocity during both the
outstroke and return strokes. Draw the profile of the cam when (a) the
axis of the follower passes through the axis of the cam shaft, and
(b) the axis of the follower is offset by 20 mm from the axis of the cam
shaft.
