Explain the construction and working principle of seismograph
Answers
Answer:
A seismograph is a device for measuring the movement of the earth, and consists of a ground-motion detection sensor, called a seismometer, coupled with a recording system.
Seismographs operate on the principle of inertia.The underlying principle of seismograph construction is to have a heavy weight suspended from a spring over a base or within a moving box.
. A simple seismometer that is sensitive to up-down motions of the earth can be understood by visualizing a weight hanging on a spring. The spring and weight are suspended from a frame that moves along with the earthʼs surface. As the earth moves, the relative motion between the weight and the earth provides a measure of the vertical ground motion. If a recording system is installed, such as a rotating drum attached to the frame, and a pen attached to the mass, this relative motion between the weight and earth can be recorded to produce a history of ground motion, called a seismogram.

Explanation:
seismograph construction
Seismographs are created by suspending a heavy weight from a sturdy frame that is attached to the ground. When the ground shakes during an earthquake, the frame shakes back and forth with it. The hefty weight, on the other hand, is not physically attached to the earth and wishes to remain stationary. As a result, the weight remains stationary while the frame swings back and forth around it. Scientists can see the relative motion of the weight and frame by the markings created by placing a pen on the weight and paper on the frame, resulting in a seismogram.
Seismograph principles
Seismographs work on the theory of inertia, which states that stationary objects, like as the weight in the above image, will remain immobile unless a force is applied to them.
