@princewilliam1293 2 years Viscosity index is defined as the rate of change of viscosity due to change in temperature
@chaithuchowdary3135 2 years Change of viscosity of a lubrican with respect to temperature A good lubricant must be stable at higher as well as lower temperatures
@bhushan797 2 years Wrong answer. The currect answer is "viscosity index is a measure of how the viscosity of a fluid changes with temperature"
Modulus of Rigidity is what he is answering
Kam se kam sahi tho answer de do bhai
😮
Are chomiu
resistance to the flow of liquid with temp.. is vI

Wait what is thus for?
Indeed it's the rasio of siar istress per unit the siar istrain rate

Ye shear stress / per unit shear strength kya hota hai
