Formula One. The 2023 Pirelli tyres include (from left to right) the three slicks – called the softs, mediums, and hards – intermediates, and full wets. Formula One tyres are specialised racing tyres designed for use on a Formula One car. These tyres play a crucial role in the car's performance, affecting grip, handling, and overall speed.
An F1 car can be no more than 200 cm wide and 95 cm tall. [ 1] Though there is no maximum length, other rules set indirect limits on these dimensions, and nearly every aspect of the car carries size regulations; consequently the various cars tend to be very close to the same size. The car and driver must together weigh at least 798 kg as of 2024.
To take a common example, 195/55R16 would mean that the nominal width of the tire is approximately 195 mm at the widest point, the height of the side-wall of the tire is 55% of the width (107 mm in this example) and that the tire fits 16-inch-diameter (410 mm) rims. The code gives a direct calculation of the theoretical diameter of the tire.
Modern road tires have several measurements associated with their size as specified by tire codes like 225/70R14. The first number in the code (e.g., "225") represents the nominal tire width in millimeters. This is followed by the aspect ratio (e.g.,"70"), which is the height of the sidewall expressed as a percentage of the nominal tire width.
A modern-day Ferrari Formula One car being tested by Fernando Alonso at Jerez. The car is the Ferrari F10. In recent years, most Formula One teams have tried to emulate Ferrari's 'narrow waist' design, where the rear of the car is made as narrow and low as possible. This reduces drag and maximises the amount of air available to the rear wing.
The Federal-Aid Highway Act Amendments of 1974 established the bridge formula as law, along with the gross weight limit of 80,000 pounds (36,000 kg). Current applications of the formula allow for up to 7 axles and 86 feet or more length between axle sets, and a maximum load of 105,500 lbs. [ 2]
List of moments of inertia. Moment of inertia, denoted by I, measures the extent to which an object resists rotational acceleration about a particular axis, it is the rotational analogue to mass (which determines an object's resistance to linear acceleration ). The moments of inertia of a mass have units of dimension ML 2 ( [mass] × [length] 2 ).
A road car usually has a ride height around 16–17 cm (6.3–6.7 in), while an SUV usually lies around 19–22 cm (7.5–8.7 in). Two well-known extremes are the Ferrari F40 with a 12.5 cm (4.9 in) ride height [ 1] and the Hummer H1 with a 40.64 cm (16.0 in) ride height. [citation needed] The table below provides average ride height for ...
