Dismantle Bullock Cart: Project assigned to me.
There was a time when india has many bullock carts (BC). BC were used to carry tonnes of agricultural products to nearby market. But all the BC were made of wood. When government banned cutting of trees due to ecological reasons, wood for BC became scarce. CTARA intervened and made a steel BC.

Advantages:
  1. Whole cart was dismantable, so can be packed in compact boxes for transportation. Now whether the manfacturer in Vada actually transported them ti far-off places is to be investigated. According to Prof. Date, 6 BC could be transferred in truck of capacity 1 ton. 
  2. Use of hollow steel pipes helped in reduction of weight of steel BC to ~150 Kg, ~100Kg less from the traditional wooden BC.
  3. The BC has a feature of suspension spring enabling the BC to negotiate bumps, holes in the rough village road without passing the shock to the riders. How suspension coil does that is to be investigated.
  4. The BC has a feature of shoe-brakes to aid in de-accelerating the BC esp. during downhill.
  5. The yoke had a feature to move sideways to tackle bulls having different walking speed and updown for bulls of different heights. But the farmers wanted to still use wooden yoke as they wanted their bulls not to get in contact with steel. The reason was not understood. One reason could be steel getting hot in sun and making bull uncomfortable.
Still to investiage:
  1. Tensile strength of steel compared to wood / bamboo / Iron.
  2. Requirement of bullock cart to be dismantable.
  3. How spring work as shock absorber.
Tensile Strength of
Steel (assuming mild steel was used) is 841 with density 7.58
Steel (assuming mild steel was used) is 841 with density 7.58

If Modiji becomes PM then Rank 9 is Rank 1!!!





To my dear politically active friends,

I know that we all sincerely want a better India and for a better India we have voted for the right person after using all our wisdom. After all the logical and emotional calculations, we have expressed our solidarity and trust to a particular party (AAP, BJP, Cong, Regional Parties) and have voted for it or have motivated others to vote for it.

I think many of us have been fooled in believing that Modi ji will change the face of India. That he ALONE is sufficient and will transform India to a "Ram Rajya" or good governance country.

But if a Modi ji led BJP government was not able to do wonders in Gujrat itself, is it fair to except magical transformations from his central government.

In this election BJP's PR strategy has fooled many. BJP itself admits that it has spent 700+ crore rupees on AD campaign alone in this 2014 LS elections.

We have been fooled into believing that Gujrat is a Model state whose development model can be copy pasted by all the states in India. But sadly BJP's PR can't change economic facts. Similar PR strategies of India Shining was adopted by Vajpayee ji government in 2004 LS elections which has badly backfired.

These two articles which appeared in TheHindu, The Gujarat muddle and The Gujarat middle written by development economist Jean Drèze, the economist behind much celebrated NREGA program, basically concludes that Gujrat is not a Model state and ranks 9th in most of the Development Indexes.

Some excerpt from both the articles

"If Modi ji becomes PM of India, please don't expect much from him or BJP. In this elections, objective facts and rational enquiry are taking a holiday and the public relations (PR) industry is taking over."

"Gujarat is doing a little better than the all-India average in many respects, but there is nothing there that justifies it being called a “model.” Anyone who doubts this can download the latest National Family Health Survey report, or the Raghuram Rajan Committee report, and verify the facts."


"Further, it focusses on performance in the decade of the 2000s, when Gujarat was supposed to be at its best. Surely, Gujarat will fare well this time? On the contrary, it slips from 9th to 12th in the ranking of 20 major States"

Now after some time (may be few minutes or hours) computer center server will activate your LDAP ID. You can verify by going to GPO and entering your LDAP ID and Password. If GPO is opening, then your account is activated.

2) If you dont have LAN cable, First try to purchase it from your hostel shop, if it is not there then purchase it from H7, H12 general shop. Ask someone for direction to these shops if required.

3) After connecting the LAN cable to LAN port of the computer and LAN switch given in your room, you must configure your computer with proper LAN setting and your browser (firefox, chrome, internet explorer) with proper proxy setting.

4) To find out your IP address, take help of your some one in your wing who has access to internet or take help of IP allocation algorithm.
Find IP address of hostel room for mentioned hostels using the links: H1, H2, H4, H5, H6, H8, H9H11, H13, H14

5) Now change your LAN setting in Windows 7, 8 machine.

6) After proper LAN setting, configure your browser with proxy setting of proxy server of IITB.
For Internet Explorer, Chrome, Firefox.

Congrats, now you are ready for using internet facilities at IIT Bombay.

7) Type URL (may be www.google.com) in address bar of browser and press ENTER.
A popup like this will appear
Enter your LDAP ID as username and date of birth (in format DDMMYYYY) as password.

If google page comes up, great otherwise review if you have everything properly as mentioned in steps up or take help of any of friend, iscp companion or ismp mentor or some senior.
