What is metacentre ?

Metacentre is defined as the point about which a body in a liquid starts oscillating when the body is tilted by a small angle.

It's also defined as the point at which the line of action of the force of buoyancy will meet the normal axis of the body when the body is given a small angular displacement.

G - centre of gravity

B - centre of buoyancy

Centre of buoyancy is shifted after tilting it.

Force of buoyancy acts vertical. It meets normal axis at M.

M is the Metacentre.

Meta-centric height:-

The distance between metacentre and centre of gravity of the body is called meta-centric height.

In above figure, MG is the meta-centric height.

What is meant by "Quality of a product"?

•Quality is a relative term. It is really in the eyes of the beholder.

•From functional point of view, product is considered to be of good quality if it meets the desired functional requirements adequately over the intended period of its use.

The Dimensions of Quality

•Quality is characterized by multiple dimensions as follows:

01. Performance        : Primary operating characteristics.

02. Features              : Secondary operating characteristics.

03. Time                    : Time waiting in line, time from concept to production of a new product, time to complete a service.

04. Reliability             : Extent of failure free operation.

05. Durability             : Amount of use until replacement is preferable to repair.

06. Uniformity            : Low variations among the repeated outcomes of a process.

07. Consistency         : Match with documentation, advertising, deadlines, or industry standards.

What is the Qur'an ?

The Qur'an is the last scripture that has been revealed to mankind by the Lord Creator and Protector. It was through the Last Messenger, Muhammad (s), that the world first heard of it. It certainly is the divine scripture that is to be accepted by all, upto the very last man.

The term ‘Qur'an’ has the meanings of ‘the recitation’, or ‘that which is to be recited’ and of ‘that which is recited.’ Indeed, the Qur'an itself has employed the connotation ‘the scripture that is recited’ in connection with this term (13:31). Unlike the earlier scriptures, the Qur'an is never a compilation of legal pronouncements or code of laws (Taurat), or hymns (Zaboor) or a collection of Gospel or good news (Injeel). It is highly probable that the Qur'an has been named as the last scripture because each one of its words is to be repeatedly read by thousands upon thousands of its believers and is to be so etched into their hearts so as to mould their very lives according to its guidelines. As for the actual reason, it is the Lord Who sent it Who knows the answer thereof.
