## formulas that use Three Member Frame - Pin/Pin Top Horizontal Point Load

\(\large{ R_A = R_D = \frac{P\;h}{L} }\) | |

\(\large{ H_A = H_D = \frac{P}{2} }\) | |

\(\large{ M_B = M_C = \frac{P\;h}{2} }\) |

### Where:

\(\large{ h }\) = height of frame

\(\large{ H }\) = horizontal reaction load at bearing point

\(\large{ M }\) = maximum bending moment

\(\large{ A, B, C, D }\) = points of intersection on frame

\(\large{ R }\) = reaction load at bearing point

\(\large{ L }\) = span length of the bending member

\(\large{ P }\) = total concentrated load
