Dear, if the value is zero, then neither positive nor negative is it. Zero means zero without sign.... But thumb rule is if the slope is zero then the moment may be maximum at that location
Dear Friend, Similar triangle rule is of Basic Trigonometry in which comparative values is taken For ordinate at unknown distance "x", have fond value 10x/EI Which is described in example. At distance 4.8m, value of ordinate is 48/EI hence if converted in per m lengh, value by distance is the 10/EI And at unknown distance "x" final value is "10/EI" as per m value multiply by "x" hence the final value is "10x/EI hope now you get the point
And for your second query, Its exactly the value as "reaction at respective support in real beam multiplied by "x" and divided by flexural rigidity as "EI"
Dear Mr. Capone Generally deflection is calculated under the application of point load but It may be differentiated as deflection at a particular location while maximum deflection point is having the value as max in every location of that particular beam.... It may happen that at location of point load or simply say loading, deflection having value "X" while at any other point of beam as "Y" in which Y>X Hope your query is now resolved
Please in the case where the max bending moment is zero,will you treat it as negative?
Dear, if the value is zero, then neither positive nor negative is it. Zero means zero without sign.... But thumb rule is if the slope is zero then the moment may be maximum at that location
How did u get 10x/ei on similar traingle was it reaction at Ra in real beam multiplied by X?
Dear Friend,
Similar triangle rule is of Basic Trigonometry in which comparative values is taken
For ordinate at unknown distance "x", have fond value 10x/EI Which is described in example.
At distance 4.8m, value of ordinate is 48/EI hence if converted in per m lengh, value by distance is the 10/EI
And at unknown distance "x" final value is "10/EI" as per m value multiply by "x" hence the final value is "10x/EI
hope now you get the point
And for your second query,
Its exactly the value as "reaction at respective support in real beam multiplied by "x" and divided by flexural rigidity as "EI"
What is the difference between deflection and maximum deflection?
Dear Mr. Capone
Generally deflection is calculated under the application of point load but
It may be differentiated as deflection at a particular location while maximum deflection point is having the value as max in every location of that particular beam....
It may happen that at location of point load or simply say loading, deflection having value "X" while at any other point of beam as "Y" in which Y>X
Hope your query is now resolved
great
