How do you calculate the equivalent spring constant for springs in parallel?
Use the formula:
What is the first step in solving a problem involving spring forces?
Draw a free-body diagram showing all forces acting on the object, including the spring force.
What happens when a spring is stretched (positive Δx)?
The spring exerts a force pulling it back towards its equilibrium position (negative force).
What happens when a spring is compressed (negative Δx)?
The spring exerts a force pushing it back towards its equilibrium position (positive force).
What is the effect of increasing the spring constant (k)?
The spring becomes stiffer, requiring more force to stretch or compress it by the same amount.
What is the effect of stretching a spring beyond its elastic limit?
The spring will deform permanently and not return to its original length.
What is the effect of the negative sign in Hooke's Law?
The spring force always opposes the direction of displacement, acting as a restoring force.
What is the effect of stretching a spring?
The spring exerts a restoring force inwards, pulling back towards its equilibrium position.
What is the effect of compressing a spring?
The spring exerts a restoring force outwards, pushing back towards its equilibrium position.
What happens to the equivalent spring constant when more springs are added in parallel?
The equivalent spring constant increases, making the system stiffer.
What happens to the equivalent spring constant when more springs are added in series?
The equivalent spring constant decreases, making the system more compliant.
What is the effect of the negative sign in Hooke's Law?
The spring force always opposes the displacement.
