Pressure measuring plates are useful for quantifying the pressure patterns under a foot over time but cannot quantify horizontal or shear components of the applied forces. [ 2 ] The measurements from a force platform can be either studied in isolation, or combined with other data, such as limb kinematics to understand the principles of locomotion.
The weight stack on a selectorized cable machine; in this example, each plate weighs 6 kg. Weight machines commonly use specialized sets of plates (called "weight stacks"), consisting of a set of rectangular plates mounted on rails. Through a cable and pulley system, the burden is transferred to the machine's user.
Excess or reduced body weight is regarded as an indicator of determining a person's health, with body volume measurement providing an extra dimension by calculating the distribution of body weight. Average adult human weight varies by continent, from about 60 kg (130 lb) in Asia and Africa to about 80 kg (180 lb) in North America, with men on ...
Typically, it is written in the form x/y, where x is the percentage of weight in the front, and y is the percentage in the back. In a vehicle which relies on gravity in some way, weight distribution directly affects a variety of vehicle characteristics, including handling, acceleration, traction, and component life. For this reason weight ...
In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below). For example, a 25-foot (7.6 m) three-axle dump truck would have a gross weight limit of 54,500 pounds (24,700 kg), instead of 80,000 pounds (36,000 kg), which is the standard weight limit for 63-foot (19.2 m) five-axle tractor-trailer. [1]
Thus 50 kg (~491 N) of plates will apply to the user only an equaling weight of 18 kg or a force of ~174 N at the beginning of the motion. On the other end of the spectrum may be a bent-over-row machine that is designed with the user's grip between the plates and the fulcrum.

The ground pressure of motorized vehicles is often compared with the ground pressure of a human foot, which can be 60 – 80 kPa while walking or as much as 13 MPa for a person in spike heels. [ 3 ] Increasing the size of the contact area on the ground (the footprint ) in relation to the weight decreases the unit ground pressure.
