couples though unequal do not disturb theequilibrium, for they merely produce unequal strains atthe fixed points A and B, and do not alter the effect ofthe other forces. III. TOGGLE-JOINT. 198. Toggle-Joint. Fig. 143 represents two combinedlevers, AB, BC, forming what is called a toggle-joint. They… … Fig. 143. force P to act vertically downward at B against the resis-tances R and R; if the system is in equilibrium, we have,by Art. 133, P sin ABC __ sin 2a __ 2 sin a cos aR ~~ sin PBC ~ sin a sin a = 2 cos a. But the effective resistance Q is only one component ofR, the other being supplied by…
