The volume of blood in the ventricle at the end of diastole.

involves the inertia forces of inflowing blood into the left atrium during diastole which stretch its fibers, thus storing mechanical energy in them; more stretched fibers (increased preload) contract during systole with a higher force (a mechanically produced an increase in contractility known as the Frank-Starling Law)

The pressure inside the left ventricle at the end of diastole; determined by venous return and myocardial contractility and relaxation.

The tension created in a fastener when first tightened. Reduces after a period of time due to embedding and other factors.

used to set the suspension ride height. Not enough droop (too much preload) and the suspension will tend not to want to move initially, causing a rough ride over small obstacles such as stutter bumps. Too much droop (not enough preload) and the vehicle loses valuable travel, bottoming out easier and can cause stability problems. Any suspension (stock or aftermarket) can benefit from proper ride height adjustment.

Preload is the control that adjusts the amount of sag in a suspension system (front or rear). Preload is adjustable on even the cheapest equipment and is usually achieved by altering the amount of air in the positive air chamber of an air sprung system, or winding on / off the preload ring that compresses the spring on a coil sprung system.

preload is an adaptive readahead daemon. It monitors applications that users run, and by analyzing this data, predicts what applications users might run, and fetches those binaries and their dependencies into memory for faster startup times.

Free Linux program written by Behdad Esfahbod which runs as a daemon and records statistics about usage of programs using Markov chains; files of more frequently-used programs are, during a computer's spare time, loaded into memory. This results in faster application startup times as less data needs to be fetched from disk. preload is often paired with prelink.

The use of one group of bearing balls set in opposition to another to remove axial lash or backlash and increase ball bearing screw stiffness. All axial freedom is eliminated in preloading.

Process in which controlled pressure is exerted on a component such as a bearing or ball joint before the normal operating load is imposed.

The force resulting from negative operating clearance or negative bearing internal clearance in rolling bearings.

A small amount of current drawn from a power supply to stabilize its operation. Preloads are usually provided by a bleeder resistor.

A feature that allows the estimate preparer to create reusable files with data common to many estimates (e.g. remarks, labor rates, etc.).

As a noun, Preload refers to an operation in a package center where packages are sorted and loaded into vehicles for delivery, prior to the drivers reporting to work. As a verb, preload refers to the process of placing packages into a vehicle in stop-for-stop delivery order prior to a driver reporting to work.
