Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.

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.

3. GPS
S8P3. Students will investigate relationship between force, mass,
and the motion of objects.
c. Demonstrate the effect of simple machines (lever, inclined plane,
pulley, wedge, screw, and wheel and axle) on work.
4. Work
• Work is the application of a force to an object to move it a certain
distance in the direction of the force.
• Formula
work = force x distance or W = F x D
5. Force
A force is a push or a pull
A force is measured in Newtons (N)
6. Distance
• An amount that an object travels
• Measured in meters (m)
1 meter*
* Not drawn to scale
7. Work
• Work is done only when an object moves in the same direction of the
force that is being applied.
• NO movement!!!!
NO work!!!!
• Example:
• Picture a person wearing a backpack and climbing up the side of a mountain,
the person is doing work because the direction of motion and force being
applied are both upward. (same direction)
8. Work
• Work is not always done when a force is applied to an object.
• Example
• A brick wall will not move no matter how much force you apply with your hands. The
wall does not move, no work is being done when you push on it.
9. Simple Machines
Six basic types
Designed to make
work easier by changing the
size or direction of a force
Have some moving
parts
Can combine to
form compound machines
10. Simple Machines – Inclined Plane
An inclined plane is a straight,
slanted surface.
Example:
• A ramp is a stationary inclined
plane.
It is easier to push an object up
a ramp than it is to lift the
same object straight up to the
same height.
11. Simple Machines - Wedge
• A wedge is an inclined plane
that is wider or thicker at one
end than at the other.
• Example: Knife blade or axe
• When moved it is used to cut,
split, or pry apart objects
12. Simple Machines - Screw
A screw is an inclined plane that is
wrapped around a cylinder.
Screw, bottle cap
• When turned a small force is applied
over the long distance of the screws
threads
The amount of work for a screw
depends on the number of thread,
which is actually the length of the
inclined plane
13. Simple Machines – A Lever
• What is it? Made up of a bar
that pivots at a fixed point
called a fulcrum
• The force applied to a lever is
called the effort.
• The object moved is the load.
• They are classified into three
different groups
• The groups are based upon the
locations of the fulcrum, load,
and the input force
14. Simple Machines - Levers
• In a first class lever, the fulcrum is in the middle, load and
force on the ends
• Example: seesaws
• In a second class lever, the load (resistance) is in the
middle, force and fulcrum are on the ends. Example:
nutcracker, wheelbarrow
• In a third class lever, the force (effort) is in the middle,
the load and fulcrum are on the ends. Example: baseball bat or
fishing rod
15. Simple Machines - Pulleys
• A pulley is a rope or chain
wrapped around a wheel.
• A load is attached to one end of
the rope and a force is applied
to the other end of the rope.
16. Pulley
A double pulley makes work easier
not only by changing the direction of
the force, but also by multiplying the
effort
A single pulley makes work easier
by changing the direction of the
effort force
• When you pull down on the rope, the
load moves up
17. Simple Machines – Wheel & Axel
• A wheel and axle is a simple
machine that consists of two
circular objects of different
sizes.
• The wheel is always larger
than the axle
• Example: door knob
• By getting more force from
the effort put in when
compared to the amount of
distance

Eduardo needs an inclined plane
(a ramp) to carry the boxes out of the truck.
29. There is a flagpole outside Eduardo’s new
school. What simple machine could be used
to raise and lower the flag?
A pulley is used to raise and
lower the flag.
30. Eduardo’s mom wants to hang a cabinet in
the new kitchen. What simple machine might
she use to attach it to the wall?
