thu width of cylinders as nearly as possible equal to that of the wheels.
206. We have, then, the following easy, approximately correct rules for locomotives : — ^If r is lengfth of crank, r the* distance of centres of gravity of each balance weight from centre of wheel, e the distance apart of the centre lines of cylinders, d the distance apart of the wheels or centres of gravity of the balance weights, w the total weight of crank (referred to the pin, see Art. 205), pin, connecting rod, p...iston, slide, and piston-rod, a the angle which the radius to centre of gra\ity of balance weight makes with near crank : — (1.) luside-cylinder engines with uncoupled wheels.
Each balance weight = 1^^ V 2^*T2^, 80 that A is easily obtained from a book of tables.
(2.) Outside-cy Under single engines with uncoupled wheels.
Each balance weight «= tDB A= 180'; 00 that in this case the balance weight is placed exactly opposite to the crank.
(3.) Inside-cylinder engines with wheels coupled. Find by rule (1) if the weight of the coupling rods, &c., is too great.
