Hooke's Law and Moments Flashcards
What is the extension of a spring proportional to?
The extension of a spring is directly proportional to the load
State the equation for Hooke’s Law that starts with force applied (F)?
F=kx
What is force applied measured in?
Newtons (N)
What is spring constant measured in?
Newton per meters (N/m)
What is extension measured in?
Metres (m)
What does a large spring constant indicate?
It indicates a stiff spring
What does a small spring constant indicate?
A small spring constant indicates a loose spring
What is the point called at which an object stops obeying Hooke’s Law?
Elastic Limit
What is the moment of a force?
A measure of its turning affect
Two forces of same size can cause different amounts of rotation. True or False?
True
State the equation that starts with Moment?
Moment=Fd
What are moments measured in?
