6.14 through 6.17 Use the moment-area method to determine the slopes, and deflections at points *B* and *C* of the beam shown.

FIG. P6.17, P6.43

To determine

Find the slope *B* and *C* of the given beam using the moment-area method.

Given information:

The Young’s modulus (*E*) is 29,000 ksi.

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 *D*;

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*;

Determine the bending moment at *C*;

Determine the moment at *D*;

Show the

Show the elastic curve diagram as in Figure (4).

Refer Figure (3).

Determine the deflection at *D* using the relation;

Here,

Substitute 9 ft for

Determine the slope at point *A* using the relation;

Here, *L* is the length of the beam.

Substitute 36 ft for *L*.

Determine the slope at point *B* using the relation;

Here, *b* is the width of the triangle and *h* is the height of the triangle.

Substitute *b*, and *h*.

Substitute 29,000 ksi for *E* and *I*.

Hence, the slope at *B* is

Determine the deflection at point *B* using the relation;

Here, *A* and *B*, *A* and *B*, *b* is the width of triangle, and *h* is the height of the triangle.

Substitute 9.0 ft for *b*, and *h*.
