Guy R. Gregg (born December 14, 1949, Brooklyn, New York) is an American Republican Party politician, who served in the New Jersey General Assembly from 1992–2008, where he represented the 24th Legislative District. He was a candidate for the Republican nomination for United States Senator in 2002.[1]
Gregg served in the Assembly as Republican Conference Leader from 2004–2006, was the Majority Whip from 1998–1999 and the Assistant Majority Whip from 1996-1998. He served in the Assembly on the Human Services Committee and the Labor Committee.[2]
After nearly 40 years in the New Jersey Legislature — making him the longest-serving legislator in New Jersey history — Robert Littell announced on March 6, 2007, that he would not seek reelection to the New Jersey Senate and would retire from office at the end of 2007. Republican Freeholder Steve Oroho and Assemblyman Guy R. Gregg both announced that they would pursue the Republican nomination for Littell's Senate seat in the June 2007 primary.[3] Gregg lost the primary election to Steve Oroho, who was backed by the Littell family [4]
Career
[edit]As an Assemblyman, Gregg has sponsored legislation eliminating New Jersey's duplicative Sub Chapter S Corporation Tax as well as legislation which would allow vendors to retain 1% of the sales tax they collect, as compensation for administrative costs. The Assemblyman has also sponsored the 10-20-Life Law which permits extended penalties for offenders using weapons during the course of committing a crime. The Assemblyman advocates the 65 mph speed limit increase which he authored, as well as increased mass transportation for the area of the state.
In 2002, Gregg said he would seek the Republican nomination for U.S. Senator.[1] But he dropped out of the race on filing day and endorsed Jim Treffinger, the Essex County Executive and the front runner.[5] Treffinger himself dropped out less than a week later after FBI agents raided his office as part of a big time scandal that later sent Treffinger to jail.
Gregg served in the United States Marine Corps from 1972–1975, achieving the rank of First Lieutenant.[2]
Gregg graduated with a B.A. in 1972 from Monmouth College in Psychology.[2] He was born in Brooklyn, New York, and currently resides in Long Valley in Washington Township, Morris County, New Jersey.[6]
District 24
[edit]Each of the forty districts in the New Jersey Legislature has one representative in the New Jersey Senate and two members in the New Jersey General Assembly. The other representatives from the 24th Legislative District for the 2006-2008 legislative session were:
- Assemblywoman Alison Littell McHose, and
- Senator Robert Littell

Radial Force Variation, or Road Force Variation [1] (RFV) is a property of a tireTire uniformity that characterizes its behavior in terms of steering, traction, braking and load support. High values of RFV for a given tire reflect a high level of manufacturing variations in the tire structure that will impart ride disturbances into the vehicle in the vertical direction. RFV is measured according to processes specified by the ASTM International in ASTM F1806 – Standard Practice for Tire Testing.
Explanation
[edit]RFV can best be explained by example. Assume a perfectly uniform tire mounted on a perfectly round wheel loaded with a constant force against a perfectly round test wheel. As the wheel turns, it turns the tire, and the tire carcass undergoes repeated deformation and recovery as it enters and exits the contact area. If we measure the radial force between the tire and the wheel we will see zero change as the tire turns. If we now test a typical production tire we will see the radial force vary as the tire turns. This variation will be induced by two primary mechanisms, variation in the thickness of the tire, and variation in the elastomeric properties of the tire.
Consider a good tire with RFV of 6 pounds. This tire will induce a 6 pound force upward into the vehicle every rotation. The frequency of the force will increase in direct proportion to rotating speed. Tire makers test tires at the point of manufacture to verify that the RFV is within allowable quality limits. Tires that exceed these limits may be scrapped or sold to markets that do not require stringent quality.
Spring Model
[edit]RFV is often explained by modelling the tire as being a ring composed of short compression springs. As the tire turns a spring element makes contact with the road and is compressed. [2] As the spring rotates out of the contact area it recovers to its original length. In practice, these springs have slight differences in their lengths and spring constants. These variations result in RFV.
Tires are complex composite structures made of many different components that are assembled on a drum and cured in a mold. As a result there are many conditions that result in RFV. These include variations in: tread extrusion thickness and symmetry, tread splice, body ply splices, inner liner splice, bead symmetry, turn-up symmetry, building drum alignment, transfer ring alignment, curing press bead seating, shaping bladder alignment and control, mold runout, and mold alignment. All of these factors can lead to variations in the material distribution and thickness that are modelled as spring length. The various tire components also are made from different materials, each of which exhibit variation in their elastic properties. These variations are influenced by rubber viscoelastic properties, mixing dispersion and uniformity, and cure heat history, among other things.
Waveform Analysis
[edit]RFV is a complex waveform. It is expressed using several standard methods, including peak-to-peak, first harmonic, second harmonic, and higher-order harmonics. In production RFV testing these are reported as both magnitudes and angles.
