Unlike the roller-delayed blowback military Heckler & Koch rifles the cocking handle is situated far more rearward and on the right side and features a camming system to help overcome the initial friction exerted by the "bolt head locking lever" anti-bounce mechanism that prevents the bolt from bouncing off the barrel's breech surface.

The MLB (Modularer Längsbaukasten in German) or MLP (Modular Longitudinal Platform) component matrix is used in the B8 (A4, A5, Q5), C7 (A6, A7, Q7) and D4 (A8) families of Audi vehicles. This is noteworthy for placing the front differential ahead of the clutch, allowing the front axle to be moved forward 4 inches. This results in an increase in wheelbase and a slightly more rearward weight distribution for better vehicle dynamics.

In comparison, trail braking splits up the peak force the tire is able to generate partially toward braking (longitudinal force acting on a tangent to the direction of travel,) and partially toward steering (lateral force acting perpendicular to direction of travel.) See the traction circle for more info. The combined vector force acting on the vehicle's center of gravity accelerates it in a more rearward direction as shown in the illustration. This causes the vehicle to travel on an Euler spiral-shaped path of constant radius and speed reduction.

Casts of Denversaurus and Tyrannosaurus In 2010, American paleontologist Gregory S. Paul estimated the length of Denversaurus at six meters and its weight at three tonnes. American paleontologist Robert T. Bakker considered Denversaurus distinct from Edmontonia and Chassternbergia in having a skull that was wide at the rear and a more rearward position of the eye sockets. The holotype skull has a length of 496 millimetres and a rear width of 346 millimetres. In the referred specimen AMNH 3076 these proportions are less extreme, measuring 395 millimetres long with a rear width of 220 millimetre.

The new PTM (Porsche Traction Management) system incorporates a clutch-based system which varies the amount of torque to the wheels to avoid tire slippage. According to Porsche, redirecting torque to control oversteer or understeer results in neutral handling as well as greatly improved performance in all weather conditions. For the face lifted 2010 model year 911 Turbo, known internally as the 997.2 (as opposed to the 997.1 2007-2009 model years), launched in August 2009, the PTM system was tweaked to give a more rearward power bias. The paddle shifters for the PDK double-clutch gearbox debuted on the Turbo.

Fisher no-draft individually controlled vent windows were a new standard feature. Sales fell further to 953 cars. The 1934 Series 370D was restyled yet again but this time was mounted on a completely new chassis. The radiator grill slanted rearward with a central bar and five horizontal sections, the windshield sloped even more rearward, headlights were enclosed in new teardrop housings mounted on streamlined supports, the horns joined the radiator cap under the hood, the spare tire was concealed under a new beaver tail deck on most models and the whole car sat approximately lower.

During corner entry the front tires, in addition to generating part of the lateral force required to accelerate the car's centre of mass into the turn, also generate a torque about the car's vertical axis that starts the car rotating into the turn. However, the lateral force being generated by the rear tires is acting in the opposite torsional sense, trying to rotate the car out of the turn. For this reason, a car with "50/50" weight distribution will understeer on initial corner entry. To avoid this problem, sports and racing cars often have a more rearward weight distribution.

The Heckler & Koch SL7 is a roller-delayed blowback operated sporting carbine made by Heckler & Koch. It was chambered in 7.62×51mm NATO caliber and designed and marketed throughout the world as a hunting/utility rifle. Unlike the roller-delayed blowback military Heckler & Koch rifles the cocking handle is situated far more rearward and on the right side and features a camming system to help overcome the initial friction exerted by the "bolt head locking lever" anti-bounce mechanism that prevents the bolt from bouncing off the barrel's breech surface. The SL7 is no longer manufactured, having been replaced by the Heckler & Koch SLB 2000.

These changes included modifications to the engine and its surroundings (lighter internal parts, more rearward tilt to optimize the front weight distribution, new turbo and new exhaust system), but the most significant change was made to the suspensions: now both the front and rear suspensions were MacPhersons, and also bigger wheel arches were implanted, allowing more suspension travel. However, the drivetrain remained the same as before, and when Tommi Mäkinen left the team at the end of 2001, the new drivers couldn't get on with this special transmission, which required an aggressive left-foot braking approach. The original Evo WRC (sometimes referred to as Step1) was replaced with the Step2 from 2002 Finland onwards.

This causes the pilot to have to push forward on the elevator controls, increasing the camber of the upper surface of the horizontal stabilizer/elevator (tailplane) surface. The resulting decrease in loading on the front wing then allows the front wing to fly at a lower angle of attack, farther away from an aerodynamic "stall". This can also allow less induced drag by the wing, and hence a greater cruise speed for a given power setting. Even if the aircraft loading is not changed to a more rearward CG, flying with the elevator trimmed for nose up results in having to hold forward force on the controls, which causes the elevator trim tab to increase the camber of the tailplane upper surface (albeit tiring, and therefore employed only in unusual or temporary circumstances, say during takeoff or in icing conditions), and hence lower the tailplane angle of attack.

Subsequent flight testing with the prototypes revealed that the SR.A/1 possessed a relatively good level of performance and handling. Its agility was publicly displayed when Tyson performed a demonstration of high-speed aerobatics and inverted flight above an international audience at the 1948 SBAC Display while piloting the type.King 14 December 1950, p. 551. During the flight test programme, two of the three prototypes suffered accidents, leading to an interruption in the trials and modifications being made to the remaining intact aircraft. TG263 appeared in a Pathé Newsreel in July 1947. TG271 appeared in a BBC Newsreel in August 1948. The SR.A/1 possessed a somewhat small and heavily-framed cockpit canopy, which provided the pilot with a poor view outside the aircraft, a particularly negative feature for a prospective fighter aircraft. Despite this, the pressurised cockpit was relatively spacious, providing enough room to accommodate an additional crew member potentially; an observer could also have been potentially seated in a more rearward position as well.Flight International 1947, p. 128.

One major advantage of the trijet design is that the wings can be located further aft on the fuselage, compared to twinjets and quadjets with all wing-mounted engines, allowing main cabin exit and entry doors to be more centrally located for quicker boarding and deplaning, ensuring shorter turnaround times. The rear-mounted engine and wings shift the aircraft's center of gravity rearwards, improving fuel efficiency, although this will also make the plane slightly less stable and more difficult to handle during takeoff and landing. (The McDonnell Douglas DC-9 twinjet and its derivatives, whose engines are mounted on pylons near the rear empennage, have similar advantages/disadvantages of the trijet design, such as the wings located further aft and a more rearward center of gravity.) Trijets are more efficient and cheaper than four-engine aircraft, as the engines are the most expensive part of the plane and having more engines consumes more fuel, particularly if quadjets and trijets share engines of similar power, making the trijet configuration more suited to a mid-size airliner compared to larger quadjets. However, higher purchase prices, primarily due to the difficulty and complexity of mounting the third engine through the tail, will somewhat negate this advantage.
