What is a tensile force?
A force that produces extension
What is a compressive force?
A force that reduces the length of a material
What is Hooke’s law?
The extension of a spring is directly proportional to the force applied, provided that the limit of proportionality is not exceeded
What does the area underneath an F against x graph equal?
The work done on the spring
What is ultimate tensile strength?
The greatest amount of stress that a material can withstand before reaching breaking point
What is a ductile material?
A material which can easily be drawn into wires
What is elastic deformation?
When the material returns to its original length after any applied force is removed
What is plastic deformation?
When the material does not return to its original length after any applied force is removed
What is the elastic limit?
The point of which elastic deformation stops happening and plastic deformation starts
How do you calculate the total force constant of springs in series?
1/k1 + 1/k2 = 1/kT
How do you calculate the total force constant of springs in parallel?
k1 + k2 = kT
