tensile and compressive forces Flashcards
1
Q
compression
A
forces push in on opposite sides to squeeze the object
2
Q
tension
A
forces pulling on opposite sides to stretch the object
3
Q
what is hooke’s law
A
the extension of a spring is directly proportional to the force
4
Q
calculation for force using springs
A
force = constant x extension
F=KX
5
Q
calculation for energy using springs
A
energy = (constant x extension squared)/2
E=(KX^2)/2
6
Q
inelastic
A
when a force is removed, the spring does not return to its original length
there is permanent deformation
7
Q
elastic deformation
A
spring returns to its original shape once force is removed
8
Q
linear
A
the graph is a straight line
9
Q
non linear
A
the graph is a curve
