Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

This flat user interface is more attractive user interface in 2017. The application is gives more important to the system functionality. The application is to manage the student’s details, driver’s details, bus details, bus route details, bus fees details and more. The application has only one unit for admin. The admin can manage the entire application. The admin can login into the application by using username and password of the admin. The application is develop for big and small colleges. It is more user friendly for non-computer person. Even they can easily learn how to manage the application within hours. The application is more secure by the admin. The system will give an effective output for the VB.Net and SQL Server given as input to the system. The compiled java program given as input to the system, after scanning the program will generate different reports. The application generates the report for users. The admin can view and download the report of the data. The application deliver the excel format reports. Because, excel formatted reports is very easy to understand the income and expense of the college bus. This application is mainly develop for windows operating system users.

2. Depending on the response of the material towards loads materials are classified as
• Elastic
• Plastic
• Rigid
Classification of materials based on deformation:
4. Stress:
Stress is the internal resistance
offered per unit area of a body
against the deformations due
the external applied load.
Units:
𝑠tress = 𝜎 =
𝑅𝑒𝑠𝑖𝑠𝑡𝑖𝑛𝑔 𝐹𝑜𝑟𝑐𝑒
𝐴𝑟e𝑎
5. TYPES OF STRESSES :
only two basic stresses exists :
• normal stress
• shear stress
Other stresses either are similar to these basic stresses or are a combination of these e.g.
bending stress is a combination tensile, compressive and shear stresses.
Torsional stress, as encountered in twisting of a shaft is a shearing stress.
Normal stresses : We have defined stress as resistive force per unit area. If the stresses are
normal to the areas concerned, then these are termed as normal stresses. The normal stresses are
generally denoted by a Greek letter ( s ).
There are two types of normal stresses namely tensile and compressive stresses
8. Shear Stress:
Denoting the shearing stress by the Greek letter 𝜏 (tau), we write
Shear Stress=
𝑺𝒉𝒆𝒂𝒓 𝒍𝒐𝒂𝒅
𝒔𝒉𝒂𝒆𝒓𝒊𝒏𝒈 𝒂𝒓𝒆𝒂
9.
10. Q1. The figure shows a support stand designed to carry downward loads. Compute the stress in the square
bar at the upper part of the stand for a load of 120 kN. The line of action of the applied load is centered on
the axis on the shaft, and the load is applied through a thick plate that distributes the force to the entire cross
section of the stand.
Compressive stress on an arbitrary cross section of support
stand shaft.
11. Stress F = 𝜎 = Force/Area = (compressive)
F = 120 kN
A = 35*35= mm2
𝜎 =
Comment This level of stress would be present at any part of any cross section of the
square shaft between its ends.
12. Q2. The Figure shows two circular rods carrying a casting weighing 11.2 kN. If each
rod is 12.0 mm in diameter and the two rods share the load equally, compute the
stress in the rods.
Given Casting weighs 11.2 kN.
Each rod carries half the load.
Rod diameter = d = 12.0 mm
14. Q3. For the punching operation shown in Figure, compute the shear stress in the material if a
force of 5500 kN is applied through the punch. The thickness of the material is 1.5 mm.
15. Given F = 5500 N;
t = 1.5 mm.
The perimeter, p =
The shear area is A=
Then, the shear stress is =
16. Strain:
Strain is found by dividing the total deformation by the original length of
the bar. The lowercase Greek letter epsilon (ε) is used to denote strain
Strain=
Total deformation
Original length
The strains are classified in to three types:
• Tensile strain
• Compressive strain
• Shear strain
