Question

Что бы сжать пружину на 6 см нужно приложить силу 120Н. Какую силу нужно приложить что бы сжать ее на 4 см?

Answer 1

F=k*x
120H=k*6. => F=20*4
k=20 F=80H
Ответ: 80H

Answer 2

Calculating the Force Required to Compress the Spring

To calculate the force required to compress the spring by 6 cm, we can use Hooke's Law, which states that the force required to compress or extend a spring is directly proportional to the displacement.

Hooke's Law can be expressed as:

F = kx

Where: - F is the force applied - k is the spring constant - x is the displacement from the equilibrium position

We are given that to compress the spring by 6 cm (0.06 m), a force of 120 N is required. We can use this information to calculate the spring constant k.

Using the formula F = kx, we can solve for k: 120 N = k * 0.06 m k = 120 N / 0.06 m k = 2000 N/m

Now that we have the spring constant k, we can use it to calculate the force required to compress the spring by 4 cm.

Calculating the Force Required to Compress the Spring by 4 cm

Using Hooke's Law (F = kx), we can calculate the force required to compress the spring by 4 cm (0.04 m) using the spring constant k we found earlier.

F = kx F = 2000 N/m * 0.04 m F = 80 N

Therefore, to compress the spring by 4 cm, a force of 80 N is required.
