1
Q
What is elastic limit?
A
The point beyond which it the force is removed the material does not return to its original length.
2
Q
Origin of upthrust
A
Change in pressure: density of fluid x g x depth of object in the fluid.
3
Q
what does young modulus measure
A
stiffness of a material
4
Q
archimedes principle
A
upthrust of an object = weight of the fluid it displaces
5
Q
upthrust equation
A
U = density of fluid x gravity x volume of displaced fluid
6
Q
if the object is fully submerged what is displaced volume of fluid?
A
volume of object
7
Q
laminar flow
A
