TD605 Poster Day
Various Project Exhibited
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:
Steel (assuming mild steel was used) is 841 with density 7.58
Steel (assuming mild steel was used) is 841 with density 7.58

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:
- 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.
- Use of hollow steel pipes helped in reduction of weight of steel BC to ~150 Kg, ~100Kg less from the traditional wooden BC.
- 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.
- The BC has a feature of shoe-brakes to aid in de-accelerating the BC esp. during downhill.
- 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.
- Tensile strength of steel compared to wood / bamboo / Iron.
- Requirement of bullock cart to be dismantable.
- How spring work as shock absorber.
