Question

№4 жесткость пружины 20H/м. Вычислите какую силу нужно приложить к пружине чтобы растянуть ее на 1см

Answer 1

Дано:

k = 20 Н/м

dx = 1 см = 0.01 м.

F - ?

Решение:

Закон Гука:

F = kd(дельта)x

F = 0.01 * 20 = 0.2 Н.

Answer 2

Calculation of the Force Required to Stretch a Spring

To calculate the force required to stretch a spring by 1 cm, we can use Hooke's Law, which states that the force exerted by a spring is directly proportional to the displacement of the spring from its equilibrium position.

Hooke's Law can be expressed as:

F = kx

Where: - F is the force applied to the spring, - k is the spring constant (also known as the stiffness of the spring), - x is the displacement of the spring from its equilibrium position.

In this case, we are given that the stiffness of the spring is 20 H/m (Hooke's constant is measured in N/m), and we want to find the force required to stretch the spring by 1 cm (0.01 m).

Using the formula, we can substitute the given values:

F = (20 H/m) * (0.01 m)

Simplifying the equation:

F = 0.2 N

Therefore, the force required to stretch the spring by 1 cm is 0.2 Newtons.
