The two wheels of the At-lantic engine, for example, carry about the sameweight. The areas of contact are nearly in an in-verse ratio to the diameters. Comparing the wheelsof the cafe and dining cars, the wheel with theheavier load has much the greater weight per sq. area, showing that the metal does not yield indirect proportion to the weight, at least within thelimits of the loads here imposed. In the laboratory the first series of tests made wasto apply pressures, increasing by small increments,to the tread of a 36-in. steel wheel resting on an The lowest load applied was 500 lbs. Thiswas increased by increments of 500 lbs. up to.
