I'm stuck on the following question. I feel like I've computed the correct results but because my units have cancelled I'm a bit lost. If you refer below (I think) I have computed the correct result for a maximum deflection but I don't know what answer is the position for a maximum deflection. I think it's the first derivative but I'm not sure.
Anyway, here's the question:
If a beam of length L is fixed at the ends and loaded in the centre of the beam by a point load of F Newtons the deflection at a distance x from one end is given by:
Where E = Young's Modulus and I = Second Moment of Area of the beam. Find the position and the value of the maximum deflection of the beam if:
L = 10m
F = 100kN
Substituting x= (+5) into the initial equation for a maximum deflection:
Now I'm lost on the position?
Thanks in advance
