How do you do a spiral spring experiment?
B5-2: Experiments Using a Spiral Spring
- Measure and record the mass of the scale pan and attached pointer.
- Put 5g in the pan and record the total load (including the mass of the pan and pointer) and the pointer position.
- Put 10g more into the pan and record the position of the pointer and the total load on the spring.
What is spiral spring experiment?
Theory: If a mass ‘m’ is hanged from the end of a vertically hanged spiral spring, then the length of the spring increases by length ‘l’. In this situation, the body is assumed to be at equilibrium. Now, the body is pulled by a . distance x downward and is released, then it will execute simple harmonic motion [Figure].
What is the function of spiral spring in physics?
The spiral spring is made from flat strip or wire coiled up in the manner of the groove on a phonograph record. As a mainspring or hairspring, it provides a compact source of energy in clocks and watches; it is also used on typewriters and parking…
What is the possible errors in a spiral spring experiment?
The main cause of error in this experiment is reading the stretched length of the spring. The metre rule scale should be read at eye level directly opposite the pointer. Use the slotted base to ensure that the metre rule is vertical.
What does slope represent in a spiral spring experiment?
It is measured in units of N/m. This is a linear equation of the form y=mx+b. If we create a graph of force versus position. The slope of the line represents the spring constant k and will have units of N/m.
How does force on a spiral spring verify Hooke’s law?
F = – k x Where, (k) is the force constant of the spiral spring. The negative sign shows that the original shape of the spring can be restored. The force constant provided the elastic limit is not exceeded. The straight-line graph shows a linear relationship between the mass and the extension.
How do springs work physics?
Hooke’s Law: The Physics of Springs Hooke’s Law states that the more you deform a spring, the more force it will take to deform it further. Using the example of a common compression spring, the more you compress the spring, the more force it will take to compress it further.
How does temperature affect the spring constant of a spring experiment?
As the temperature increases, the spring constant decreases. A linear fit was made to the data to determine the spring constant. It can even be seen that the bands of data begin to spread due to creep at higher temperatures.
What information about the spring does the gradient provide?
The gradient of the line is the spring constant, k. The gradient of the graph of force F, (y-axis), and extension e, (x-axis), is equal to the spring constant k. Hooke’s Law is obeyed up to the limit of proportionality.
What is the elastic constant of the spiral spring?
How does the experiment verify Hooke’s law?
A slotted weight of m kg is added to the weight hanger and the pointer position is noted. The same procedure is repeated with every additional m kg weight. It will be observed that the extension of the spring is proportional to the weight. This verifies Hooke’s law.
What kind of force does a spring use?
The spring force is the force exerted by a compressed or stretched spring upon any object that is attached to it….Types of Forces.
| Contact Forces | Action-at-a-Distance Forces |
|---|---|
| Frictional Force | Gravitational Force |
| Tension Force | Electrical Force |
| Normal Force | Magnetic Force |
| Air Resistance Force |
What factors affect the spring constant?
Factors affecting spring constant:
- Wire diameter: The diameter of the wire of the spring.
- Coil diameter: The diameters of the coils, depending on the stiffness of the spring.
- Free length: Length of the spring from equilibrium at rest.
- The number of active coils: The number of coils that compress or stretch.
What is force constant of a spiral spring?
THEORY. When a load F suspended from lower free end of a spring hanging from a rigid support, it increases its length by amount x, then F α x or F= k x, where k is constant of proportionality. It is called the force constant or the spring constant of the spring.
How does a spring obey Hooke’s Law?
How do you find the spring constant of a spring experiment?
W = kx. W is the weight of the added mass. Therefore, the spring constant k is the slope of the straight line W versus x plot. Weight is mass times the acceleration of gravity or W = mg where g is about 980 cm/sec2.
What is the purpose of the Hookes law lab?
Purpose: The primary purpose of the lab is to study Hooke’s Law and simple harmonic motion by studying the behavior of a mass on a spring. Your goal will be to extract a measure of the stiffness of one particular spring.
What is spring force physics?
Spring force is the force required or exerted to compress or stretch a spring upon any object that is attached to it. When an object applies a force to a spring, then the spring applies an equal and opposite force to the object. It always acts so as to restore mass back toward its equilibrium position.
