Use the moment-area method to determine the slope and deflection at point *D* of the beam shown.

FIG. P6.32, P6.58

To determine

Find the slope and deflection at point *D* of the given beam using the moment-area method.

Given information:

The Young’s modulus (*E*) is 70 GPa.

The moment of inertia (*I*) is

**Calculation:**

Consider flexural rigidity *EI* of the beam is constant.

Show the free body diagram of the given beam as in Figure (1).

Refer Figure (1),

Consider upward is positive and downward is negative.

Consider clockwise is negative and counterclowise is positive.

Determine the support reaction at *A* using the Equation of equilibrium;

Determine the reaction at support *C*;

Show the reactions of the given beam as in Figure (2).

Refer Figure (2),

Determine the bending moment at *A*;

Determine the bending moment at *B*;
