e found thatha = -Bh, i.b = cc, and cc = a.t.We see therefci-e that each rod is underthe action of a pair of equal forceswhich tend to crush A b and a c, and tostretch b c ; these forces are severally proportional to a a, c c, and b b. These lines therefore measure the thrustsof A B and A c and the… … 68 THEORETICAL MECHANICS. ca, ab parallel to o b and o c respectively ; draw a d parallel to BC, dc toA.B, and join bd (tho line b dls, parallel to a c, as the student can prove),and we shall havec«, ab, ad, dc, bd containing as many units of lengthrespectively as the forces q, r, the tension of…
