Force and dynamics with a spring, numerical approach

Force and dynamics with a spring, numerical approach It may strike you as strange that one of the first forces we will discuss will be that of a spring. It is not one of the four Universal forces and we don’t use springs every day. Or do we? The basic motion of a spring is to oscillate. Many, many mechanical systems oscillate. However, they

Springs – The Physics Hypertextbook

The force needed to stretch or compress a spring is proportional to its change in length. This is known as Hooke's law and it works for many spring-like things.

$\begingroup$ Note that unless the box has mass, or there's friction between the mass and the box, the box is irrelevant. Just think of it as applying the force to the junction of the damper and the spring. The position of this (massless) pont will always the place where the three forces on it balance to zero.

Work by Variable Force, and Spring Force

The defining character of a spring is that it resists displacement from its rest position with a force which increases linearly: restoring force = - k * (displacement) where k is called the spring constant.

Hooke's law - Wikipedia

Torsion spring - Wikipedia

The weight rotates about the axis of the spring, twisting it, instead of swinging like an ordinary pendulum. The force of the spring reverses the direction of rotation, so the wheel oscillates back and forth, driven at the top by the clock's gears.

Dynamics - Hooke's Law Experiment

Hooke's Law says that the stretch of a spring is directly proportional to the applied force. (Engineers say "Stress is proportional to strain".) In symbols, F = kx, where F is the force, x is the stretch, and k is a constant of proportionality. If Hooke's Law is correct, then, the graph of force versus stretch will be a

PhysicsLAB: Springs: Hooke's Law

In 1678, Robert Hooke announced the invention of the spring scale and the relationship for elastic materials that is now known as Hooke's Law. When an object is acted upon by a force, it can be compressed, stretched or bent. If when the force is removed, the object returns to its original shape, it is said to be elastic.

Consider a spring force acting on a particle, as shown below. The spring is attached to a wall at point O, where it can pivot. At position A of the particle, the spring is stretched or compressed by an amount s 1 from its equilibrium (unstretched) position.

Statics with spring force - Physics Forums

May 03, 2017  With the pulley, the spring would still be carrying 100% of the collar's weight. If the string were pulling vertically upwards, then the spring force would be equal to the collar's weight. However, in this case there is another force besides the spring force and gravity that must be cancelled for the collar to be in equilibrium.

AP Physics 1 : Spring Force - Varsity Tutors

There are two vertical forces in play: gravity and total spring force. Since net force is zero, we know that these two general forces are equal to each other: Substituting in expressions for each force, we get: There are two things to note about the total spring force. The first is that we multiply it by 40 because there are 40 individual springs.
