An elementary treatise on mechanics, embracing the theory of statics and dynamics, and its applications to solids and fluids (1849)
Smith, Augustus William, 1802-1866 · New York, Harper · leaf 88
■2irr\ 129. EXAMPLES ON THE PRECEDING CHAPTERS. Ex. 1. Two beams, rigidly connected at a given angle, turnon a horizontal axis through their point of union; find the po-sition of equilibrium by the action of their own weights. Let AC, BC be the beams suspended from C, and making 64 STATICS. … with each oth-er the angle a.Since C is afixed point, theonly conditionof equilibriumis, that the sumof the momentsabout C is zero (Art. 75). Let glt g2 be the centers of gravity of the beams, and g^C=a,g2C = b. Also, w1 = weight of AC, acting at g-^and w2 =weight of BC, acting at g2. Draw through…
