Hooke's Law Flashcards
What is hooke’s law?
it says that extension of a spring is proportional to the force applied up to a given load
Equation for hooke;’s law?
F = kx where k is a constant representing the spring stiffness
What is k called ?
The spring constant
What must there be for material to stretch or twist?
a pair of opposite forces acting on it
What must there be for a material to compress?
A pair of forces acting in the same direction on an object
What are the units of a spring constant?
Nm^-1
What is a compressive force?
One that compresses the material`
What is a tensile force>?
a force that stretches the material
When does hooke’s law stop working?
When the load (force ) is too great.
What do tensile forces create in the spring?
tension
Does hooke’s law work for both tensile and compressive forces?
YeS
