Which is occurring when work is being done?

The key factor as to when and why this work is being done is timing and involves a service resource or facility being unavailable. By contrast condition-based maintenance is not directly based on equipment age. Planned maintenance is preplanned and can be date-based based on equipment running hours or on distance travelled.

The non-mechanical work of force fields can have either positive or negative sign work being done by the system on the surroundings or vice versa. Work done by force fields can be done indefinitely slowly so as to approach the fictive reversible quasi-static ideal in …

In physics work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form it is often represented as the product of force and displacement. A force is said to do positive work if (when applied) it has a component in the direction of the displacement of the point of application. A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force. For example when a ball is held above the ground and then dropped the work done by the gr…

In physics work is the energy transferred to or from an object via the application of force along a displacement. In its simplest form it is often represented as the product of force and displacement. A force is said to do positive work if (when applied) it has a component in the direction of the displacement of the point of application. A force does negative work if it has a component opposite to the direction of the displacement at the point of application of the force. For example when a ball is held above the ground and then dropped the work done by the gravitational force on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). When the force F is constant and the angle between the force and the displacement s is θ then the work done is given by: $W=Fs\cos {\theta }$ Work is a scalar quantity so it has only magnitude and no direction. Work transfers energy from one place to another o…
