Question

Пружины в растянутом состоянии имеют длины 12 см Какова длина недеформированной пружины если удлинение равно 20 мм

Answer 1

X=x1-x=12-2=10 см Ответ:10 см

Answer 2

Calculating the Length of the Undeformed Spring

To calculate the length of the undeformed spring, we can use the formula for the elongation of a spring:

Elongation (ΔL) = k * L0

Where: - ΔL = Elongation - k = Spring constant - L0 = Original length of the spring

Given: - Elongation (ΔL) = 20 mm - Spring constant (k) = 100 N/m - Length of the spring in the stretched state = 12 cm = 120 mm

We can rearrange the formula to solve for the original length (L0): L0 = ΔL / k

Substituting the given values: L0 = 20 mm / 100 N/m = 0.2 m

So, the length of the undeformed spring is 0.2 meters.
