Which of the following is a slow rise of plastic deformation under the action of shear stresses when it is below the yield strength of the material.

a.Brittle Structure

b.Ductile fracture

c.Creep

d.Fatigue

Answers

Answer 1

Creep can be described as a process of the slow rise of plastic deformation under the action of shear stresses when it is below the yield strength of the material. Hence, Option C is correct.

What do you mean by permanent deformation?

Permanent deformation can be defined as irreversible, the deformation remains even after the elimination of the carried out forces, at the same time as the transient deformation is recoverable because it disappears after the elimination of carried out forces.

therefore, the correct statement is  Option C.

What is Newton's third regulation?

Ths  0.33 regulation states that for each movement (pressure) in nature there's an identical and contrary response. If item A exerts a pressure on item B, item B additionally exerts an identical and contrary pressure on item A. In different words, forces end result from interactions.

Weight of reflector = mg=200^ * 9.8=1960 NForce exerted with the aid of using chain =1960 NDirection = upwardsTension at the chain = weight of reflector=1960 NWeight of reflector =mg =100 * 9.8=980NMagniyof pressure reflector exerts on earth = 980 N(Due to movement response pair of forces, consistent with Newton's 0.33 regulation of motion.
