Superb explaination 🔥🔥🔥 All cleared Thank you sir
how divide into 7 equal parts
this video really helped thank you ❤
4.11 T2 -1 T2= 3.11 T2
sir where did you get 3.11?
Need a flashlight for gravitational quanta? Einstein's dream was to have such a device. Proposal for joint implementation of the invention. You are negotiating with companies that make fiber optic gyroscopes. Technical consultation and payment for the cost of the test device from me We need; assemble a hybrid fiber optic gyroscope (based on 50% - Michelson's experience 1881-2024). Use a hybrid fiber optic gyroscope and measure; 20, 25, 30 m/sec., car speed in a straight line. As a result of 100% direct experience we will receive the basis for: Postulate 1. Light is an ordered vibration of gravitational quanta. Postulate 2. The gravitational field controls the frequency and speed of light in a vacuum.
Very useful...
Sir your explanation is very clear sir compared to my college lecturer
Thank you so much sir
You are such a saviour thanks 🙏
Thanks so much
Your accent plsssss
I love u sir
thank you sir i am watch this video only 1 time no need to look twice
Thank so much mr
Thanks for best explanation
If its written nearer to observe ,does that mean that pointy side of pentagon is near to X-axis????
Wow. So. The same method for all of them. Fantastic. Do yo know the method for an external point, not on the conic? Thanks
Sir why are not using cos sin just doing the calculation by only numbers
You can use sin cos also, but first you have to determine all angles. Two steps required. Here without calculating angles problem is solved
❤❤
Thank you sir. That rubbing velocities calculation is helpful for me at this moment of time.
Thank you sir
Clear Explanation 👍
can you use trigonometry in solving this
Good video
I'm very thank you , i have about 4 month to search someone can help me . This is perfect way i hope god save you

THANK YOU FOR THE EXPLANATION SIR !!!
best video over entire internet keep up the good work.
Superb Explanation!
Best video
not good you should improve
Salute sir ❤ nice explain 🎉🎉
Sir you teach really well...i have never understood this topic so clearly! Thankyou so much 🙏🏼✨
great explanation
Dr sir displacement diagram is wrong where is the return dwell.... Actually angular displacement cam must be 360 degree
For drawing cam profile, displacement diagram of rise and return only needed. You can even eliminate dwell at top also. Also you don't need to draw rise and return angles with some scale, you can take any arbitrary length for each.
@@drjojithomas thanks sir doubt clear
I understood this so easily 😆
sir how to solve reciprocating engine probelm
deserves more views
Thank you sir🙏
thank you so much!! i'm currently writing a report on the gyroscopic couple and was quite struggled with understanding the conceptthanks for making everything clear for me! very appreciated
Please Can you explain i-value of a buckle in steel sheet
Sir what is the 2 cm of radius in last question r1,r2,r3
Question not clear, may be you are asking why have we divided by 2. To covert diameter into radius
What about normal force ?
Op sir
Great video sir. Thanks from Bangladesh
Hola🎉
Thanks sir 🙏
Excellent explication 😊
