A geometrical discontinuity in a body, such as a hole or a notch result in nonuniform distribution of stress at the vicinity of discontinuity. At the region near the discontinuity, the local stress will be higher than normal stress distribution.

A geometrical discontinuity in a body, such as a hole or a notch result in nonuniform distribution of stress at the vicinity of discontinuity. At the region near the discontinuity, the local stress will be higher than normal stress distribution. Correct Answer True

The stress concentration occurs at discontinuity. The relative cross-sectional area of a specimen with a discontinuity is lower than the sample without discontinuity. But the value of total stress remains the same for both the specimen, so the extra stress per unit area will accumulate at a discontinuity in the form of stress concentration.

In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, it has no locally detectable features. B: A black hole is a region of spacetime where gravity is so strong that nothing, no particles or even electromagnetic radiation such as light, can escape from it. C: The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. D: The boundary defining the region of space around a black hole from which no escape is possible is called the event horizon.
Seven boys are living in different buildings at a different height. Abir, Ayush, Anand, Ajay, Alok, Nakul and Nandu. Ayush is living on a higher floor than Nakul and Abir. Abir lives on a higher floor than Nakul and Alok is on the lowest floor. Nandu lives in a lower height than Ayush but higher than Abir and Nakul. Ajay is the one who lives lower than Nakul. Anand lives on a higher floor than Ayush.  Find whose building is the highest one?
The following situations involve a cluster of three or more geometrical figures. Having one or more dots placed at nay point inside the cluster. This cluster is followed by a set of four altenative figures each composed of a cluster of the same type of figures. Now. For each dot we have to observe the region in which it is enclosed i.e in Which of the geometrical figure this region is common. From amongst the figures, select the figure which satisfies the same conditions of placement of the dot as in fig. (x)
