Homework Statement
Using method of integration, determine the elastic curve for the beam and calculate the total deflection at a point A (end) of the beam. Use EI as a constant.
See word document attached with diagram.
Homework Equations
EIV''(x) = - M(x)
The Attempt at a Solution
I know how to integrate to get the deflection formula but I'm not sure how to calculate M(x) with the moment at the free end.
Is it M(x) = -w/2(L-x)^2 + M(a)(x/L)
or M(x) = -w/2(L-x)^2 + M(a)
Why do some problems in my textbook (Mechanics of materials, Gere) include the support reactions in M(x) and others don't? Do I need to include the support the reactions?
Also will my answer be in meters e.g. v = 100m/EI ?
Any help is much appreciated.
Thanks.
