Thrust-to-weight ratio – Dimensionless ratio of thrust to weight of a jet or propeller engine; Thrust vectoring – Facet of ballistics and aeronautics; Thrust reversal – Temporary diversion of an aircraft engine's thrust; Tractive effort – Mechanical engineering term that refers to the amount of traction.
Touch-down weight-bearing or Toe-touch weight-bearing: The foot or toes may touch the floor (such as to maintain balance), but not support any weight. [3] Do not place actual weight on the affected leg. Imagine having an egg underfoot that one is not to crush. Partial weight-bearing: A small amount of weight may be supported by the affected leg ...
The type of jet engine used to explain the conversion of fuel into thrust is the ramjet.It is simpler than the turbojet which is, in turn, simpler than the turbofan.It is valid to use the ramjet example because the ramjet, turbojet and turbofan core all use the same principle to produce thrust which is to accelerate the air passing through them.
Figure 1 Hard wheel rolling on and deforming a soft surface, resulting in the reaction force R from the surface having a component that opposes the motion. (W is some vertical load on the axle, F is some towing force applied to the axle, r is the wheel radius, and both friction with the ground and friction at the axle are assumed to be negligible and so are not shown.

In an idealised case, i.e. a static, uniform net force normal to level ground, this is simply the object's weight divided by contact area. 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.
