Step 1
2 * 1.4 * 3/2 + R_BC * 1.4 * cos(30°) + R_CG * 1.4 * cos(30°) = 0 -735.28 + 1.4 * 3/2 * (R_BC + R_CG) = 0 -735.28 + 2.1 * (R_BC + R_CG) = 0 2.1 * (R_BC + R_CG) = 735.28 R_BC + R_CG = 350.13 Show more…

Figure $\mathrm{P} 12.56$ shows a truss that supports a downward force of 1000 $\mathrm{N}$ applied at the point $B .$ The truss has negligible weight. The piers at $A$ and $C$ are smooth. (a) Apply the conditions of equilibrium to prove that $n_{A}=366 \mathrm{N}$ and $n_{C}=634 \mathrm{N} .$ (b) Show that, because forces act on the light truss only at the hinge joints, each bar of the truss must exert on each hinge pin only a force along the length of that bar-a force of tension or compression. (c) Find the force of tension or of compression in each of the three bars.
