...own weight. As a general rule of material beams, we may say that the strength of a beam increases as the breadth, as the square of the depth, and inversely as the length of the beam. Solid beams are weaker if the material is close around the centre, than if farther off frojp it. Solid... | |

...proportional to ^, f, and f. ( Ans. 1 (32) The load that a beam or joist will safely support varies as the breadth, as the square of the depth, and inversely as the length of the beam. If a beam 20 feet long, 3 inches wide, and 6 inches deep will support a load of 6,000 pounds, how many... | |

...of its diameter. 9. A safe load on a horizontal beam supported at its ends varies as the breadth and as the square of the depth and inversely as the length of the beam. A beam 2" x 6" x 12', on îdge, will sustain a load of 700 Ibs. What load will a beam of the same material... | |
