Edge dislocations have _____ stress field therefore _____ interactions can occur between parallel edge dislocations. Correct Answer unsymmetrical, a number of

Edge dislocations show unsymmetrical stress field. Because above slip plane atoms are in compression state and below in tension state. This stress gives a number of interactions between parallel edge dislocations.

Tresca or maximum-shear stress criteria assumes that yielding occurs when the maximum shear stress reaches a value of the shear stress in the uniaxial tension test. Assume the principal stress being σ1, σ2, σ3 where σ1 is largest, and σ3 is the smallest principal stresses. Find the value of minimum shear stress to cause yielding, given that yield stress in tension is equal to σo?

By studying all following options, select a pair that uses most closely similar reasoning. a. Researchers have looked at the communication between different animals and found that meerkats have a series of alerts and calls that fail into two categories, greetings and alarms. Since we can be sure that this meerkat is not calling as a greeting, we must accept that he is attempting to raise the alarm. b. Farmers must choose between using organic or non-organic fertilisers on their land. Organic fertilisers can produce a lower crop yield and farmers may find it difficult to change to organic methods if they have been using non-organic methods for some time. Farmers should, therefore, consider the longer-term impacts of their decisions. c. Either young persons are getting cleverer each year or examinations are becoming easier for students to pass. Since there is very little evidence from IQ testing and other supposed benchmarks that young persons are more intelligent now than in the past, we must conclude that the examination system is easier for students today than it was in the past. d. Closed wood burning chulhas are a better way to cook your food than open fire chulhas. Closed wood burning chulhas are highly efficient, whereas the open fire of open fire chulhas loses a great deal of heat in the air. More people should, therefore, use closed wood burning chulhas in their homes.
Principle: If an injury is the result of a reasonably foreseeable cause, the person/authority responsible is liable for damages because he has a duty to take reasonable measures to prevent it.
Facts: Janet, a housewife standing at her balcony, was struck on the head by a ball that flew out of a cricket field across her home. Janet sues the District Cricket Association (DCA), the owner of the cricket field for public nuisance and negligence on the ground that the field did not have a fence high enough to prevent such occurrence. District Cricket Association (DCA) claims that only about 10 balls had escaped the field in the previous 10 years and it was therefore an unforeseeable risk. Is there a duty on the part of the District Cricket Association (DCA) to prevent the risk? Is the District Cricket Association (DCA) liable to compensate Janet?
