## Homework Statement

For the beam and loading, draw the shear and bending moment diagrams. Find the max and min abs vals of shear and bending moment.

+= pointing upwards, - = pointing downwards

The beam is 1.4m long.

Load A = -.54kN at x=0,

Load B= pin support at x=.2m (Found to be +1.8kN)

load C= -1.35kN, x= .7m

load D= roller support at x= 1.1m (Found to be .63kN)

load E= -.54 kN at x= 1.4m

## The Attempt at a Solution

Im shooting myself in the foot over this because its so simple and I've reworked it about 500 times and keep getting conflicting answers... The bending moment should be the same for the same point regardless of what side i take it from, but i keep getting different values....

going from left end of beam, fixing right side.

From 0<x<.2 --> B.M = -540*x

From .2<x<.7 --> B.M = -540*x + 1800*(x-.2)

Now go from right side, fixing left end.

From 0<x<.3 --> B.M = -(540)*x

From .3<x<.7 --> B.M = -540*x + 630*(x-.3)

I am getting conflicting values for x=.7m for my bending moment... what am i doing wrong, someone please help before i go crazy...
