God bless you.

@@DrShripalSharma thanks sirji ❤️

Thank you for understanding the experiment.

Thank you very much for your sincere studies. Good bless you

Dear Student Dev Ji, I appreciate your positive attitude towards your studies. Keep it up in the future as well for your bright career. My wishes are with you.

@@DrShripalSharma thnak you sir🙏

Very nice.

Thank you 😊sir

Thank you for your sincerity. Keep it up. Very nice 👍👍

Question is not very clear but as I sense, the nok (pointed end) of the spherometer screw touch the Beam. I think, you are right. Thank you for asking the question.

Weight badhane par, beam ki bending badhati hai (depression ka badhana swabhavik hai). Thus, spherometer reading changes naturally. Try to understand. Thank you.

@@DrShripalSharma to sir beam bending badhne par spherometer ki reading badhni chahiye na lekin yaha. ghat rahi hai aesa kyo😑

@@bhimaurya don't confuse. You note the difference between the observations and consider it as increase in the values of depression. This is practicality.

@@DrShripalSharmaBut sir my professor(allahabad university) does not check He says that is wrong.If you increase the weight then spherometer reading should be increased.what should I do?😔😔😔

@@bhimaurya It depends upon the setting of the spherometer. If it is increasing mode, it will increase accordingly. No problem. You have to check it in your laboratory. Otherwise, you discuss with your professor.

Very nice 👍 Thank you for your sincere studies. Material of this beam is wrought iron.

@@DrShripalSharma I did this experiment but the value I got is 13 .87 i. e. Equal to Y of Cast iron and Y of Wrought iron is 19. Is it alright sir???

@@atulsingh4471 l think, the beam material in your lab may be cast iron. Ask about it. Thank you

@@DrShripalSharma sir thank you can u Tell me how to identify a wrought and cast iron??

Very good.

No problem.

Ok thank u sir

@@DrShripalSharma Thankyou Sir

Thank you very much for your sincerity. Due to the arrangement of spherometer scale. No problem. However, for observations you have to note the difference between the readings.

Sir due to decreasing value grap will be decreasing show,but concept of banding is say when load is increasing then bent is also increasing

No, as you think. But, with the change of mass, the condition becomes different. Only at the same settings if the observations are repeated, the mean values are to be taken. Thank you for thinking on the subject.

Dear student, No need to make a video for graph. You can see the formula used in the experiment that l, b, d for the given beam are constant and M is directly proportional to the values of obtained values of delta in the experiment. By ploting M values at x-axis and the corresponding delta values at you-axis, a straight line will be obtained. The slope of this line may be used in calculating the value of 'Y'. If you have still any doubt, you ask to me.

Sir slope kaisi hogi +ve or -ve.

@@bhimaurya +ve

@@DrShripalSharma sir lekin yaha jo reading aa rahi hai usme to weight increase karne karne par spherometer ki reading decrease kar rahi hai to slope +ve kaise hogi🤔🤔🤔🤔😑😑😑😑😑

@@bhimaurya The difference is increasing. You can check your observations.

You are right. It was recorded by my normal mobile camera at that time. Thank you very much for your real comment.

Thank you for your sincere studies ☺️
