Development Of Tipper Unloading MechanismIRJET Journal
1. The document describes the development of a tipper unloading mechanism to allow a tipper truck to unload material in multiple directions rather than just the rear.
2. Currently, tipper trucks can only unload material out the back, which reduces efficiency when precise unloading locations are required. It also requires the truck be parked in certain positions.
3. The proposed design involves adding two additional hydraulic cylinders on the sides of the tipper bed, allowing material to be unloaded to the left or right as well as the rear. This would provide more flexibility in unloading location without repositioning the truck.
4. Calculations are provided for the existing rear unloading mechanism involving the hydraulic cylinder, motor,

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.

Financial Assets: Debit vs Equity Securities.pptxWrito-Finance
financial assets represent claim for future benefit or cash. Financial assets are formed by establishing contracts between participants. These financial assets are used for collection of huge amounts of money for business purposes.
Two major Types: Debt Securities and Equity Securities.
Debt Securities are Also known as fixed-income securities or instruments. The type of assets is formed by establishing contracts between investor and issuer of the asset.
• The first type of Debit securities is BONDS. Bonds are issued by corporations and government (both local and national government).
• The second important type of Debit security is NOTES. Apart from similarities associated with notes and bonds, notes have shorter term maturity.
• The 3rd important type of Debit security is TRESURY BILLS. These securities have short-term ranging from three months, six months, and one year. Issuer of such securities are governments.
• Above discussed debit securities are mostly issued by governments and corporations. CERTIFICATE OF DEPOSITS CDs are issued by Banks and Financial Institutions. Risk factor associated with CDs gets reduced when issued by reputable institutions or Banks.
Following are the risk attached with debt securities: Credit risk, interest rate risk and currency risk
There are no fixed maturity dates in such securities, and asset’s value is determined by company’s performance. There are two major types of equity securities: common stock and preferred stock.
Common Stock: These are simple equity securities and bear no complexities which the preferred stock bears. Holders of such securities or instrument have the voting rights when it comes to select the company’s board of director or the business decisions to be made.
Preferred Stock: Preferred stocks are sometime referred to as hybrid securities, because it contains elements of both debit security and equity security. Preferred stock confers ownership rights to security holder that is why it is equity instrument
<a href="https://www.writofinance.com/equity-securities-features-types-risk/" >Equity securities </a> as a whole is used for capital funding for companies. Companies have multiple expenses to cover. Potential growth of company is required in competitive market. So, these securities are used for capital generation, and then uses it for company’s growth.
Concluding remarks
Both are employed in business. Businesses are often established through debit securities, then what is the need for equity securities. Companies have to cover multiple expenses and expansion of business. They can also use equity instruments for repayment of debits. So, there are multiple uses for securities. As an investor, you need tools for analysis. Investment decisions are made by carefully analyzing the market. For better analysis of the stock market, investors often employ financial analysis of companies.

1. Introduction of METRO RAIL in INDIA
Rapid transits in India consist of Metro, Monorails and light rail system
How it Began
India’s 1st and Asia’s 5th Metro rail was introduced in Kolkata in 1984
Delhi Metro was India's first modern metro which began its operation in 2002.
Rapid Metro Rail Gurgaon, which started operations in November 2013, is India's first privately owned & operated metro.
2. Why is it Needed ?
Unprecedented growth of personal Vehicle
Growing Traffic Congestion
Air pollution and traffic accidents has become a major concern
To avoid congestion at Peak hour
Time saving and Reduced fuel consumption

26. Step:1 Erect all the segments of the span and do final pre-stressing as per specification in drawing.
27. Step:2 Ensure that erection of all span is completed in all aspects. Release all suspenders from erected span and lower the span
on temporary bearing placed on pier cap.
29. Step:4 Release the middle support from the span and with the help of slider beam shift the middle support nearer to the front
support on segment S1 as shown in drawing.
30. Step:5 Activate the jacks of middle support on segment S1 and anchor with the span.
31. Step:6 Release the Rear support from the span and with the help of slider beam shift the rear support to the erected span of
segment S1.
32. Step:7 Activate the jacks of rear support on segment S1 and anchor with the span.
34. Step:9 Ensure that middle and rear support are firmly anchored with the span. Now close the telescopic leg of front support so
that all load transferred to the middle and rear support.
35. Step:10 Ensure all the supports firmly anchored with the span and make sure that rear trolley free from anchorage from the
span.
36. Step:11 Ensure that all supports firmly anchored with super structure. Start Auto-launching and auto launch the launching
girder by 1200mm. Check that all supports are firmly anchored or not.
37. Step:12 Now again start auto launching until rear trolley come nearer to the rear support.
38. Step:13 With the help of slider beam move rear support near to the middle support and anchored it with the span.
40. Step:15 Open the telescopic leg of front support and activate it. Anchor firmly with pier cap.
41.
42. Step: 1 Make sure that launching Girder is ready for erection of new span and lifting of segments. Now move the sliding
towards the next span to be erected near front support as shown.
45. Step:4 Fix the lifting beam and temporary pre-stressing beam on segment S1. Now lift the pier segment S1 with the help of
lifting hoist. Now move the slider in position to lift the S1 segment.
46. Step:5 Connect the S1 with the slider beam and move it nearer to the middle support.
59. Step: Lift the segment S5 and move it near the segment S6.Now same do same procedure for segment S4.
60. Step:17 Now do dry/wet matching and temporary pre-stressing and follow the procedure for final pre-stressing as per
specification given in drawing.
