Study the following statements.i) The displacement method is more useful when degree of kinematic indeterminacy is greater than the degree of static indeterminacy.ii) The displacement method is more useful when degree of kinematic indeterminacy is less than the degree of static indeterminacy.iii) The force method is more useful when degree of static indeterminacy is greater than the degree of kinematic indeterminacy.iv) The force method is more useful when degree of static indeterminacy is less than the degree of kinematic indeterminacy.The correct answer is
The rear window of an automobile is made of thick glass i.e. AB = 5 mm and thermal conductivity is 0.8 W/m degree. To defrost this window, a thin transparent film type heating element has been fixed to its inner surface. For the conditions given below, determine the electric power that must be provided per unit area of window if a temperature 5 degree Celsius is maintained at its outer surface. Interior air temperature and the corresponding surface coefficient are 20 degree Celsius and 12 W/m2 degree. Surrounding air temperature and the corresponding surface coefficient are – 15 degree Celsius and 70 W/m2 degree. Electric heater provides uniform heat flux
During heat treatment, cylindrical pieces of 25 mm diameter, 30 mm height and at 30 degree Celsius are placed in a furnace at 750 degree Celsius with convective coefficient 80 W/m2 degree. Calculate the time required to heat the pieces to 600 degree Celsius. Assume the following property values Density = 7850 kg /m3 Specific heat = 480 J/kg K Conductivity = 40 W/m degree
A water line is buried underground in dry soil that has an assumed initial temperature of 4.5 degree Celsius. The pipe may have no flow through it for long period of time, yet it will not be drained in order that no freezing occurs, the pipe must be kept at a temperature not lower than 0 degree Celsius. The pipe is to be designed for a 30 hour period at the beginning of which the soil surface temperature suddenly drops to – 17 degree Celsius. Workout the minimum earth covering needed above the water pipe so as to prevent the possibility of freezing during 36 hour cold spell. The soil in which the pipe is buried has the following properties Density = 640 kg/m3 Specific heat = 1843J/kg degree Thermal conductivity = 0.345 W/m degree

Statement: Syrian President Bashar al-Assad has revealed during an interview that a direct clash between the US and Russia in Syria was narrowly avoided "by the wisdom of the Russian leadership".  Which of the following objection(s) might be a probable reason(s) for such a revelation by Syrian President Bashar al-Assad? I. Adding that Syria needs Russian support, Assad said, "At the same time we need to avoid the American foolishness in order to be able to stabilise our country". II. Adding that Syria needs American support, Assad said, "At the same time we need to avoid the American foolishness in order to be able to stabilise our country". III. Adding that Syria needs Russian support, Assad said, "At the same time we need to avoid the Russian foolishness in order to be able to stabilise our country". IV. Adding that Syria needs American support, Assad said, "At the same time we need to avoid the Russian foolishness in order to be able to stabilise our country".

Read the passage carefully and choose thebest answer to each question out of the four alternativesand click the button corresponding to it. To know language is to be able to speak it; even a childwho does not yet attend school can speak his or herlanguage. In order to speak a language it is important tolisten to it and to read a few pages in it everyday. A childpicks up language and learns to talk just as (s)he learnsto walk. Walking and talking comes naturally to a child asit grows. In our country, a child may grow up speakingmore than one language, if these languages are spoken inthe home and in the neighbourhood. we call thismultilingualism. A child speaks a language or languagesmuch before (s)he starts going to school. To know alanguage then is first of all to be able to speak it as easilyand naturally as a tree year old child does. Later on thechild will learn to read and write in that language. In orderto read and write in a language, one has to speak it. But itis possible to speak a language but not able to read orwrite in it. A baby does not speak until it is nine monthsold but it understands a few words at six months of age.It has been listening ever since it was born, and even alittle before that. So the first strategy in speaking alanguage is to listen. To know a language one must be able to?
