3. THE RESOLUTION OF SUS-PENSION—in which W represents aforce or the weight of gravitation, andP, P the resisting power or equivalentweights. Solution : P and P= half the weight Sine of angle of depression a or dwhen the angles are equal. i8 THE MECHANICAL POWERS. … 4. For unequal angles the forcesvary as the sines of the angles from thevertical, respectively. Solution : P = W X sinewy Sine (7^-^) P = W X sine v Sine (7+7) 5. In a combiaation of forcesthe resolution involves the sines ofthe varying angles. P =z •z£/ X sine7 P= W X sine vSine(7+z^) Sine(//+7)…
