When the Permanent Indus Commission could not settle Pakistan's objections to the design of the Baglihar dam, the matter was referred to a Neutral Expert, the Swiss engineer Raymond Lafitte, appointed with the help of the World Bank, who gave his determination in 2007 and allowed the project with changes…

The Bank brought India and Pakistan to the table in 1952, proposed the division of the rivers into eastern and western groups, helped to arrange the finance for Pakistan's replacement canals, and signed the treaty for the limited purposes in which it has a role, such as helping to appoint…

These are the three eastern rivers of the Indus system, and the treaty gives their waters to India for unrestricted use, which is why the Bhakra dam on the Sutlej, the Pong dam on the Beas and the Ranjit Sagar dam on the Ravi could be built.

The Indus Waters Treaty was signed at Karachi on 19 September 1960 by Prime Minister Jawaharlal Nehru of India and President Mohammad Ayub Khan of Pakistan, after nine years of negotiation begun in 1952 through the good offices of the World Bank, which signed the treaty as a third party.

In every real machine some of the work put in is used in overcoming friction between the moving parts and in lifting the parts of the machine itself, and that work leaves the system as heat and sound, so the work delivered to the load is always less than the…

A wedge is two inclined planes joined back to back, and an axe, a knife, a chisel and a nail all work on that principle: a force applied at the blunt end is turned into a much larger sideways force at the sharp edge, and the thinner and longer the…

The pitch of a screw is the distance between two consecutive threads measured along its axis, and it is also the distance through which the screw advances in one complete turn; the velocity ratio of a screw is the circumference of the circle described by the handle divided by the…

The velocity ratio of an inclined plane is the length of the slope divided by its vertical height, because the load is pushed along the whole slope while it is raised only through the height; here ten divided by two gives five, so in the ideal case an effort of…

In a single fixed pulley the rope that is pulled down moves exactly as far as the load rises, so the distance moved by the effort equals the distance moved by the load and the velocity ratio is one; the pulley gives no gain in force and is used only…

In a pair of tongs the joint is the fulcrum, the hand presses somewhere in the middle of the arms and the object held lies at the far end, so the effort is between the fulcrum and the load; the effort arm is shorter than the load arm, the mechanical…

In a wheelbarrow the wheel acts as the fulcrum, the load sits in the tray between the wheel and the hands, and the effort is applied at the handles, which is the arrangement of a second class lever; because the effort arm is always longer than the load arm, its…

A lever is a rigid bar turning about a fulcrum, and by the principle of moments the load multiplied by the load arm equals the effort multiplied by the effort arm, so a long effort arm lets a small effort balance a large load; this is the simplest way of…

Velocity ratio is defined as the distance moved by the effort divided by the distance moved by the load in the same interval of time, and because it depends only on the design of the machine it does not change with friction, unlike the mechanical advantage.

The velocity ratio is the distance moved by the effort divided by the distance moved by the load, that is ten divided by two point five, which is four.

Mechanical advantage is defined as the load divided by the effort, so the load is the mechanical advantage multiplied by the effort, that is three multiplied by fifteen, which gives forty-five units.

Periyar launched the Self-Respect Movement in the Madras Presidency in 1925 to fight caste discrimination and Brahmin dominance. Periyar had left the Congress after he felt it did little for non-Brahmins.

The Supreme Court held that privacy is an intrinsic part of the right to life and personal liberty guaranteed by Article 21.

All four are among the 22 languages listed in the Eighth Schedule. The Eighth Schedule began with 14 languages in 1950, Urdu among them.

Chaparral is the shrub vegetation of the Mediterranean climate in California, not of the cold Taiga, so this statement is incorrect.

Corals grow in clear, shallow, warm sea water with plenty of sunlight; fresh water kills them. Coral reefs are built by tiny animals called polyps, which take calcium carbonate from sea water to make hard skeletons.
