a) Linear Translation
b) Linear Deformation
c) Angular Deformation
d) Rotation
View Answer
2 - Question
When fluid element moves from one position to another and it undergoes c hange in its dimensions, what type of motion is it?
a) Linear Translation
b) Linear Deformation
c) Angular Deformation
d) Rotation
View Answer
b
Explanation: As per the definition, bodily movement of fluid element causing it to change its dimension is linear deformation.
3 - Question

a) Linear Translation
b) Linear Deformation
c) Angular Deformation
d) Rotation
View Answer
c
Explanation: As per the definition, the sum average of two angles is magnitude of angular deformation.
4 - Question
