what is the equation for hooks law
f = kx k = elastic constant for that material x = extention
1 of 16
what is hooks law
hooks law showes that the force aplied to a material is directly proportional to the extention upto the elastic limit
2 of 16
what does malliable mean
a material that has averry little elastic deformation and a large plastic deformation before breaking the graph is just a curv and no strate line
3 of 16
what is elastic deformation
after a material is streched it will go back to its original shape this is the strate line on a graph
4 of 16
what is plastic deformation
after a material is streched it will go back to its original shape
5 of 16
what is a brittle material
a material that shows no plastic deformation and verry little elastic deformation before breaking
6 of 16
what is a tough material
a material that needs a large force on it ti deform it
7 of 16
what is the equation of stress
s = f/a f = force a = cros sectional area s is measured in pa
8 of 16
what is the equation of strain
sr = x/l x = extention l = original length sr has no units
9 of 16
what is the equation for the young modulus
young modulus = stress/strain young modulus is measured in Pa
10 of 16
what is laminar flow
when a fluid flows in a strate line the velocity at any 1 point will be constant over time
11 of 16
what is turbulant flow
when the fluid mixes and the velocity at any point will change over time
12 of 16
what is formed in turbulant flow
eddie currents or werls
13 of 16
what is a hydrometer
a device that has a constant mass that will float at diferent heights in diferent dencities of liquid
14 of 16
what is terminal velosity
when an object canot exelerate any more due to viscouse drag or air resistance
15 of 16
what is the equation of stokes law
F = 6πrἠv r = radius of sphere v = velocity of sphere ἠ = coefician of velocity in Pas F = viscouse drag
