In orthopedics, weight-bearing is the amount of weight a patient puts on an injured body part. Generally, it refers to a leg, ankle or foot that has been fractured or upon which surgery has been performed, but the term can also be used to refer to resting on an arm or a wrist.
The weight-bearing status of a patient generally changes as treatment progresses, but each progression needs to be approved by the physician. [2] In many cases the easiest way to monitor a patient's weight bearing status is to use two scales, one under each foot, and to adjust the weight on each foot until the injured foot is supported the ...
Weight-bearing exercise also helps to prevent osteoporosis and to improve bone strength in those with osteoporosis. [70] For many people in rehabilitation or with an acquired disability , such as following stroke or orthopaedic surgery, strength training for weak muscles is a key factor to optimise recovery.

The dead load includes loads that are relatively constant over time, including the weight of the structure itself, and immovable fixtures such as walls, plasterboard or carpet. The roof is also a dead load. Dead loads are also known as permanent or static loads. Building materials are not dead loads until constructed in permanent position.
Tobacco use; Alcohol use; Inactivity – particularly lack of weight-bearing or resistance activities [9] [10] [11] Insufficient caloric intake – osteopenia can be connected to female athlete triad syndrome, which occurs in female athletes as a combination of energy deficiency, menstrual irregularities, and low bone mineral density.

The axle load of a wheeled vehicle is the total weight bearing on the roadway for all wheels connected to a given axle.Axle load is an important design consideration in the engineering of roadways and railways, as both are designed to tolerate a maximum weight-per-axle (axle load); exceeding the maximum rated axle load will cause damage to the roadway or railway tracks.
The weight of the empty field pack is 8 pounds. The field pack has two major sections; the sleeping bag compartment, and the main compartment. The main compartment has a false bottom that may be opened for full use of the field pack when a sleeping bag is not carried.
The overall assembly can carry more weight than a semi-floating or non-floating axle assembly because the hubs have two bearings riding on a fixed spindle. A full-floating axle can be identified by a protruding hub to which the axle shaft flange is bolted. The semi-floating axle setup is commonly used on half-ton and lighter 4×4 trucks in the ...
