TUESDAY; JANUARY 15, 1963 Research Revie Wheel Lock Causes Hazards of Skidding . Skidding, one of the worst haz ards to plague motorists on the highway, is involved in at least 35 to 45 per cent of the accidents in the Eastern United States. This road: hazard is currently under study at the University and is part of the Automotive Re search Program, which was organ ized in 1955. .IN BRAKING, a skid develops because one or more wheels lock, Wolfgang E. Meyer, professor of mechanical engineering and head of this research program, said. "The most effective means of preventing wheel lock and in suring rapid stops is to make sure that high friction between tire and pavement is maintained even though the pavement is wet," Meyer said. Hartwig W. Kummer, research assistant of mechanical engineer ing, developed a full-scale tester that consists of a single-wheeled trailer towed by a light truck and adapted to measure the force de veloped when the trailer is locked. The testing device attracted the attention of the Pennsylvania Department of Highways and led to the establishment of a coopera tive' project with the University that is known as the Joint Road Friction Project.

THE DAILY .COLLEGIAN, UNIVERSITY PARK, PENNSYLVANIA Using this tester, the joint pro ject has measured more than 5,000 sections of pavement in a 4,000- mile skid-resistance survey. A similar testing device, cur rently under construction, will be turned over to the Department of High Ways. WITH THIS DEVICE, the De partment will be able to deter mine periodically the skid re sistance of various roads and dif ferent pavements and to study how the skid resistance of various pavements changes from year to year under varying traffic densi ties. It is known that the inclusion of small, hard particles in softer material will make a pavement skid resistant for longer periods, Meyer said. However, more must be learned about the wear-pro cess before it will be possible to design skid-resistant pavements economically from locally abun dant materials, he added. show in the HUB ... enter the pi gamrria alpha student art competition January 21, 1963 and until Tuesday, January 22 Located on the Ground Floor of HUB Tourist Trade Destroys Amish Towns The tourist - trade, which brings "outsiders"! into the Old Order Amish areas, is destroying these communities, John A. Hostetler, professor of sociology at the Ogontz campus; said recently. Speaking at a meeting of the American Anthropological Asso ciation, Hostetler, who is Amish by birth, cited the "commercial ization" of the Amish in Lancaster County as one example where the tourist trade in destroying that group's "self-respect."

The younger Amish generation, seeking higher education, has be gun to scrutinize the charter which calls for the Amish to live close to the soil and apart from the rest of the world, he said. The adult Amish, Hostetler added, are becoming aware of signs of stress and change within their communities. Fathers are having difficulty in controlling their children who, under the in fluence of "outsiders," are obtain ing drivers' licenses mid auto mobiles.- These moves help to bring about the breakdown of the Amish communities, he said. The "outsiders who take ad vantage of the Amish young peo ple," according to Hostetler, are helping the younger Amish gener ation in their trend toward be coming a part of American so ciety without the knowledge of their- parents or church, Sure is a difference between good, sound reasons and reasons That sound good.
