# Problem 863 | Deflection by Three-Moment Equation

**Problem 863**

For the beam shown in Fig. P-863, determine the value of EIδ midway between the supports and at the left end.

**Answer**

$\delta = \dfrac{1066.67}{EI} ~ \text{ upward}$

At the left end

$\delta = \dfrac{16,000}{EI} ~ \text{ downward}$
