FOCAL POINT DETERMINATION
Product Description
Experiments:
- The coefficient of damping K
- Relaxation time t.
- The quality factor Q of a damped simple harmonic motion using a simple pendulum.
Acircular disc of 8 inch dia 12 mm thick with leveling screw on which two 18 inch rod 9 mm thick can be fixed with thread which can be jointed at the top with a metal strip in the middle of which a chuck nut with pin vice is provided with hanging one weight 1 inch dia x 2 inch long having a pointer in the middle of the weight at lower side. a pointer is fixed in the middle of the base plate also. A graduated 360 degree scale made of perspex or metal is fixed on the base plate(optional). Any motion that repeats itself with equal time intervals is called periodic motion. Its period is the time required for one cycle of the motion. if you observe the motion of the marker in a horizontal plane-that is, viewing the turntable edge-on the marker seem to be moving back and forth along the line. the motion you see is the projection of uniform circular motion onto a diameter and is called simple harmonic motion.
FEATURES
Some of the factors affecting the moment of inertia are given below:
- The position of the rotational axis.
- Orientation of the rotational axis.
- Shape of the object.
- Size of the object
-
Mass distribution of mass of the object about the
rotational axis.
