The slope becomes

shear ordinates change sign and become increasingly larger negatively, the

moment diagram slopes correspondingly more steeply down to the right.

The slope becomes

**zero**where the shear ordinate is**zero**. Note also that after theshear ordinates change sign and become increasingly larger negatively, the

moment diagram slopes correspondingly more steeply down to the right.

Replacing the uniformly distributed reaction between C and D by its resultant R2

and equating moments about Rx to

**zero**, we obtain R2 = 420 lb. We then setmoments about R2 equal to

**zero**, from which Ri = 240 lb. Dividing R2 by thelength ...
