Elasticity is a property of solid by virtue of which a perticular body opposes ( the force which was applied on it) and regain its original shape and size...

How to measure dianeter of a small spherical

Aim
To measure diameter of a small sphericallcylindrical body using Vernier Callipers.

Apparatus
Vernier callipers, a spherical body (pendulum bob) or a cylinder and a magnifying lens.

Theory
If with the body between the jaws, the zero of vernier scale lies ahead of Nth. division of main scale, then main scale reading (M.S.R.) = N.
If nth division of vernier scale coincides with any division of main scale, then vernier scale reading (V.S.R.)
= n x (L.C.) (L.C. is least count of vernier callipers)
= n x (V.C.) (V.C. is vernier constant of vernier callipers)
Total reading, T.R. = M.S.R. + V.S.R. (L.C. = V.C.)
= N + n x (V.C.).

Diagram

Procedure

Determine the vernier constant (V.C.) i.e. least count (L.C.) of the vernier callipers and record it step wise.
Bring the movable jaw BD in close contact with the fixed jaw AC and find the zero error. Do it three times and record them. If there is no zero error, record zero error nil.
Open the jaws, place the sphere or cylinder between the two jaws A and B and adjust the jaw DB, such that it gently grips the body without any undue pressure on it. Tight the screw S attached to the vernier scale V.
Note the position of the zero mark of the vernier scale on the main scale. Record the main scale reading just before the zero mark of the vernier scale. This reading (1ST) is called main scale reading (M.S.R.).
Note the number (n) of the vernier scale division which coincides with some division of the main scale.
Repeat steps 4 and 5 after rotating the body by 90° for measuring the diameter in a perpendicular direction.
Repeat steps 3, 4, 5 and 6 for three different positions. Record the observations in each set in a tabular form.
Find total reading and apply zero correction.
Take mean of different values of diameter and show that in the result with proper unit.

The compressor constricts the refrigerant vapor, raising its pressure and temperature, and pushes it into the coils of the condenser on the outside of the refrigerator. ... The refrigerant absorbs the heat inside the fridge when it flows through the evaporator coils, cooling down the air inside the fridge.

Priya Dharshini ? 6 years, 9 months ago

In simple words...Radius of gyration is defined as the distance from the axis of rotation to a point where the total mass of the body is supposed to be concentrated, so that the moment of inertia about the axis may remain the same. Simply, gyration is the distribution of the components of an object. Derivation is little bit hard for me to send. Pics cant be send by students

It is a property of light in which light coming from source strike an interface and after striking ,it will bend in same medium in such a manner that angle of incidence and reflection are equal. ☺️☺️☺️ Refraction. Light coming from source strike an interface and after striking light will enter in second medium.If second medium is denser, it will bend towards normal. If rarer ,light will bend away from normal.???
