LAW IF MOTION |S FIGURED UPON FUR
 NEW STUDEBAKERS
(By Robert C. Greth)

By Robert C. Greth)
 Many years ago the noted scientist, Sir Isaac Newton, propounded ms famous laws of motion. one Of which IS to the effect that flor every force. there is an equal and opposite force. Because of this law. and the principle involved. automobile engineers must pay particular attention to the distr1- button of weight in designing motor car that will render maximum motor ing satisfaction. The balance or an automobile must be so periect that every road shock, rut, stone, chuck hoIe' etc. will be met and absorbed wlth the least discomfort to passengers ana minimum of strain on fineiy aoJusteu parts.
 To provide for the comfort of the passengers and to protect the 'nous ands of parts and the tires against sudden strains and severe shocks' Studebaker engineers have taken un usual care to design the chassis, springs and running gears or the new series 19 light six so that there IS practically no difference in the num- her of hounds of load coming on any one of the four wheels. The so-called unsprung weight has been reduced to a minimum. In other words, practl- callv the entire load. except the simple. light weight, semi floating Studebaker rear axle, is carried above the springs and this rear axle is made of such excellent and tough alloy steels that there is practically no possibility Of hreakage through road shocks or crys- talization during the ordinary life Of ] the car.
 The greatest part of the dead welght is supported in the center of the chassis on the rigid and strong rear engine supports and sub frame. Two purposes are thus served in the perfect balance of the light six There being very lit tie load carried directly above the rear wheels 1t has been possible for Stude- baker to provide an unusually roomy body on the comparatively short wheelbase of 119 inches. That is why the light six comfortably seats three large adults in it's tonneau with perfect l ease and plenty of room to stretch out, and vet not throw more than the pro- portionate share of the load on the two rear wheels. Then, too. by concentrat- | ing the dead load at the center of the chassis. the flexibility of the chassis | side members over half their length | from the central point of support to | rear wheels. added to the normal ac- l.tion of the extra long semi elliptic | springs. gives added protection to all | moving parts and saves the passen- | gers from sudden shocks and twists by absorbing all the inequalities of the | road
 | The difference in the effect pro- 1 duced from concentrating the weight at a central point or dividing it so that | a greater part of it comes directly from jumping on spring board at its | mid point between two rigid supports and jumping upon the board directly above either of the supports. In one | case there is the soft. easy spring ac- ton of the board and in the other case there is the sudden jarring and sting ing effect coming from absolute rig | idity.
 l The result of eliminating the un- sprung weight, and effecting a perfect | balance over the four wheels meani increased tire mileage. longer life axles. bearings. gears. etc. and much greater comfort to passengers.
 Because of the absence of any great load at either end of the chassis of the light six. practically all tendency te side sway or whip from one side of the road to the other is eliminated. The center of the load being in the center
 of the chassis there is no difficulty
 whatever for the driver of Studebakel light six to keep his car in the road al all times. Of course, without the abil
 ity to construct car as light in weigh
 as the new series 19 Stakeholder ligh
 six, Studebaker engineers would nevel
 have attained such perfect balance an(
 roadability in any type of vehicle.
