First , 1st solution, the author taking moment about 2m from A?
secondly, the 800Nm is clockwise moment, so it is positive? why the 2400Nm on the right(anticlockwise moment) is also positive?
i think the 2400Nm anticlockwise moment should be negative, which is located under the x-axis of graph , am i right? in the second solution here, why the 400Nm is drawn from A to 2m away from A? why not the entire length of beam?The 400nm act along the entire length of beam? Is it true?
