The Newtonian fluid has the following velocity field:
= x²yî + 2xy²ĵ - yz³k̂
The rate shear deformation ε_yz at the point x = –2, y = –1 and z = 2 for the given flow is

1. –6
2. –2
3. –12
4. 4

Correct Option: A

V = x⊃î + 2xy²zĵ - yz²̂k
Shear strain

_yz =	1		δv	+	δw		=	1	(2xy² - z³)
	2		δz		δy			2

at (–2π, 2), we get

_yz =	1	(- 4 - 8)) = - 6
	2
