[00:00:00]Mastermind's So This is easy.

[00:00:13]Topic mechanical properties of solids.

[00:00:20]So here Young's modulus Young's modulus is force per unit area by delta L by L.

[00:00:28]So force per unit area longitudinal stress to the longitudinal strain.

[00:00:33]FL by A delta L. FL by A delta L is this is A is 2.

[00:00:40]Here A is 2. So this is the Next bulk modulus.

[00:00:46]Delta V by delta V by V.

[00:00:50]So reciprocal of bulk modulus is compressibility. Delta V by V by delta P.

[00:00:56]So bulk modulus Compressibility reciprocal of bulk modulus. Poisson's ratio sigma equal to lateral strain to the longitudinal strain. Delta diameter to the diameter to the delta length to the length.

[00:01:14]So delta V by delta L into L by V.

[00:01:21]So A B C. Here A is 2.

[00:01:25]B is 3.

[00:01:26]C is 4.

[00:01:30]So easy question.

[00:01:40]So this you can able to remember.
