Thank You sir .. for this great effort.... I was very much comfortable with the the first sign convention from the beginning but after understanding that you are going to follow the second one from now onwards I decided to follow that....

Sir,
At time stamp 47:31
How come we can know that M+delta(M) and V+delta(V) is as per the direction shown in the example the cut out section of lenght delta(x)
If in the above section the direction of M+delta(M) and V+delta(V) is reversed we cannot arrive at the outcome equation
Please explain the logic behind the consideration of the direction
Regards

Great lecture ❤️

[@AmarSingh-kk3kx]

Sir please do not miss the middle steps and directly right the answers because sometimes getting confused.

I don't mean to sound like an asshole, but if u cant do such simple calculations, u need to revise highschool physics textbooks, if they have to repeat highschool level physics/mathematics every time we will never finish the course lol.

[@user-lo6fg9ym7r]

great sir

A conceptual question if someone may answer : How can something called "force per unit length" be a continuous function as shown. Meaning what this function essentially means is for every value of x ; which are essentially discrete points on the x - axis ; there exists a value y, called force per unit length? How is force "per unit length" defined for a point ? I believe it can't be defined for discrete points? Has anyone got an explanation? Please do share 🙏

[@Inquisite1031]

it simply means at distance x from the origin there is a force y, and who said the function representing force on a beam is always continuous ? it can be discontinuous, it can even be discontinuous and not be defined for all values of x.
