SPRING : Let's Learn the Character of the Physical Concept
Before going into the main review and descriptionl, please note the reason why we are obliged to learn character education. At present, education in Aceh has two main sides in the improvement of character education and education
Character education is very important lived millennium generation buddies in the face of the life of the modern era as it is today.
On this occasion, we will discuss another physics concept of an object that can stretch and return to its original form, the spring. What character can we take from this thing?
Surely we are familiar with springs. We can find this item in a mechanical pen or pencil that we use to write or balance the spring to weigh.
Spring is one example of elastic objects. That is, the object if given disturbance (style) will return to its original form. On the other hand, there is the nature of objects that when given the disorder cannot return to its original form, called plastic. Here's an illustration that illustrates elastic objects.
State of the ingredients before being given a style, b. The state of the material after given the F style. For example, an object has a length of L0 and a cross-sectional area A. After being drawn with force F, it will have a length increase of ΔL. When the force or disorder is released, the object will return to its original shape.
If a spring is hung and weighed (m), it will increase in length (DL). The larger the load (m), the greater the length (DL) changes experienced by the spring. The ratio of the load to the change of length is fixed. This fixed value is called the spring constant (k). Consider the following illustration.
(a) Spring before being loaded, (b) The spring after being loaded will increase in length.
Let's explore more deeply the physics concept of springs with symbols. The weighted load (m) has a gravity of w = m.g, where w is gravity, m is the load or mass of the object, and g is the acceleration of earth's gravity.
Here are some description of quantities and units:
k = spring constant (m/n)
w = gravity (n)
n = mass of objects (kg)
g = earth's gravitational acceleration (m/s2)
ΔL = L = L0 = long change (m)
symbol (reads: delta) is a symbol that has a meaning change or final condition minus awa state.
From the above explanation it can be seen that each spring has its own spring constant. Suppose a spring has a constant of 100 \ rm {N / m}, meaning that when the spring is given a load of 100 \ rm {N} (about 10 \ rm {kg}, if g = 10 \ rm {m / s ^ 2}) , the length increase will be 1 \ rm {m}.
Please note that each spring has a maximum load limit. If the spring is given a load that exceeds the maximum load limit, its elastic properties will be damaged so that the spring can not return to its original shape perfectly.
For example springs of a pen or mechanical pencil with a maximum load limit of 0.05 \ rm {kg} we use to lift a basketball of mass of 0.5 \ rm {kg}. What happened? At first, its elastic properties will be disturbed. The spring will be stretched, elongated and damaged. When given a greater burden, it is likely that the spring will break.
Then, what if in the learning activity, we are required to hang a load of 1.2 \ rm {kg} using a spring? Suppose there are two kinds of springs with a maximum load of 0.8 \ rm {kg} and 0.6 \ rm {kg}.
Thus, to be able to withstand the load, we can assemble both springs and hang them in parallel so that the maximum load limit becomes 1.4 \ rm {kg}. If the spring is paralleled, the load will be split equally on each spring, and bear the burden according to its ability. This treatment, of course, will not make the spring damaged.
(a) Two springs arranged in parallel, (b) A sprinter parallel springs.
Characters that can be learned from springs in everyday life are related when we are given a burden that exceeds our ability. Will we be able to do it ourselves? Of course not, but we can apply the concept of spring to work together in achieving the same goal.
To achieve goals beyond the limits of ability, we can collaborate with others to achieve goals. Do your best according to our abilities, and learn to work with others.
The various jobs and responsibilities that exceed our abilities can be solved by working together so that it will feel lighter. A well known African proverb makes it important and valuable to work together, "If you want to go fast, go alone. If you want to go far, go together. "If you want to go fast, do it alone. If you want to go far, do it together.
