by the resistance of the fixed point O, and the otherin the direction c q, parallel to B P. It follows, now, from theequality of O c and O b, that the lever can be in equilibriumonly when the force F equals that component of the force Fwhich acts in the direction c q. Let us suppose that F=c Q,and… … Pig. 41. 100 CHEMICAL PHYSICS. F : Oa=:F : Ob. [65.] It is, then, also a condition of equilibrium, that the two forcesshould be to each other inversely as the lengths of the arms ofthe lever, the point which was to be proved. We have provedthe validity of the three conditions of equilibrium for the…
