1. The axis of rotation fixed by the axle is common to both wheels. Such a design can keep the wheel positions steady under heavy stress, and can therefore heavy loads.
2. Over time their general-purpose commercial use reduced to specialist roles, as platform trucks, forklift trucks, tow tractors and urban delivery vehicles, such the iconic British milk float.
3. Mechanics encompasses the movement of all matter in the universe under the four fundamental interactions (or forces): gravity, the strong and weak interactions, and the electromagnetic .
4. The amount of work required to achieve a set objective is constant; however the force required can be reduced provided the lesser force applied over a longer distance.
5. The development of technology may draw upon many fields of knowledge, including scientific, engineering, mathematical, linguistic, and historical knowledge, to some practical result.
6. A rope passes around it, with one end attached to a fixed point above, e.g. a barn roof rafter, and a pulling force is applied upward to the other end the two lengths parallel.
7. The use of alcohol as a fuel for internal combustion engines, either alone or in combination with other fuels, has been given much attention mostly because of its possible environmental and long-term economical over fossil fuel.
8. Diesel engines will take in air only, and shortly before peak compression, a small quantity of diesel fuel is sprayed into the cylinder via a fuel injector that allows the fuel instantly ignite.
9. The variation in the camber of the road is the principal difficulty to be overcome once basic tricycle is mastered.
10.Competition among 'share' auto-wallahs has led to the virtual standardization of fare per passenger on their destination.
