Adding Parallel Fdrces

Using the parallelogram rule on not quite force F2 acting at P, Together with the couple T. Loosely speaking, we have moved the force F1 sideways to P and added the couple T to compensate for the move. So If there is another skew force at P we can now add F1 to it. We can also do this manipulation in reverse, moving from figure 3c to figure 3a. The couple T represents a purely rotational force, and is sometimes called a 'torque1, hence the symbol T. It is not a 'moment', as we explain later. It...

However, the organisers Insist that the series is merely 'on hiatus' until the economy Improves and that Formula Atlantic, which has been a part of the US race...

Hindsight

Passion for motor sport technology, editing Racecar Engineering is surely the dream gig. I never ceased to be amazed by the access the job brought. Whether it was the chance to spend time with Gordon Murray or Adrian Newey, the opportunity to work with the likes of Peter Wright and Paul van Valkenburgh, or the friendships with writers Allan Staniforth and Carroll Smith, it was all a dream ticket. Even the engineers who work within the sport are unlikely to see behind quite so many locked doors...

The 1172 Broadley Special dominated its class in 11957. For his next car Broadley again went head on with Lotus, this time in the 10Occ Sports Racing category.

Lhs mschriics of acceleration

More thoughts on the anti debate, this time taking it right back to the beginning, using pictures and purely graphic technique When a car accelerates hard, the rear usually squats down, with the body pitching backward. Conversely, when the car brakes hard the nose dives, with the body pitching forward. And when cornering, which is acceleration toward the inside of the corner, the body rolls outward, Changing the suspension geometry can cause these body motions to increase or decrease, or even...

Pre Season Testing

At the time of the lecture, the media was making a big deal of Red Bull missing the first pre-season test. How did Newey react to that 'I'm always an advocate for spending as long as possible on research and the design of the car and hopefully having a better product, which will more than compensate for the lack of development. No mid-season testing makes pre-season more important for reliability and learning about the car, and we compromise ourselves on both of those, but I believe it is the...

Safety Solutions

I read your story on head protection in open-cockpit racecars with interest. I had the opportunity to address the subject when I designed my open cockpit D-Sports racer in 1990 and a couple of situations caught my attention. First, a friend of mine was killed when he hit an Armco barrier head on. The bottom barrier gave away and the car wedged under the top rail, which came back and smashed his head. The other situation, which occurs frequently in NHRA drag racing, is cars landing upside down...

Sliding Vectors

Today we describe this property by classing forces as 'sliding' vectors. Here the force, or the arrow depicting it, can be slid anywhere along its line of action' with no change to the mechanics of the situation, Mot all vectors share this property, as we shall soon see. Also, this property most certainly does not apply if we are doing a structural analysis of a body, since the stresses vary hugely according to where the forces act along their lines of action. So when considering load paths,...

The Moment Of A Force At A Point

6 we see that wherever we slide force F along its line of action, it always gives the same moment M at the arbitrary point P. The vector product and its moment can replace the second axiom of statics given earlier. Modern vector theory is used in many different fields besides mechanics, such as structural engineering, aerodynamics, electrodynamics, quantum theory and more. So moments are at the core of much of modern engineering and science. However, the practical understanding of moments is...
