Q

to fail
→ failure
When structural components can
no longer resist stress, they fail.
The failure is then due to stress.

Q

force
→ to apply a force
→ to exert a force
In order to lift a weight, one needs
(to apply) force.
A force is exerted on a spring.

A

Kraft
→ Kraft anwenden
→ Kraft ausüben

17
Q

friction
→ frictional resistance
Friction between two materials
causes heat.

A

Reibung, Reibkraft
→ Reibungswiderstand

18
Q

fulcrum [fʊlkrəm]
pivot
→ to pivot
hinge
→ to hinge
Levers are grouped into three
classes depending on the position
of the fulcrum or pivot.
Doors and windows move on
hinge

A

Hebelpunkt, Drehachse
Drehpunkt, Drehachse
→ drehen, drehbar lagern
Drehachse, Drehgelenk
→ etw. (in ein Drehgelenk)
einhängen

19
Q

(force of) gravity,
gravitational force
→ centre of gravity
Gravity is a natural phenomenon
by which objects with mass
attract one another.

A

Schwerkraft, Gravitation,
Erdanziehungskraft
→ Schwerpunkt

20
Q

lever [ˈliːvə]
→ leverage (effect) [ˈliːvərɪdʒ]
→ to leverage
A lever boosts the force needed to
turn an object. This mechanical
advantage is called leverage.

A

Hebel
→ Hebelkraft, Hebelwirkung
→ hebeln, aushebeln, in
Schwung bringen

21
Q

load
Usually several loads act on
structural components.

A

Belastung, Last,
Beanspruchung

22
Q

magnitude
A force has both magnitude and
direction; to calculate the
magnitude of a load, one must
know the direction of the load

A

Größe, Ausmaß, Stärke
Größenordnung

23
Q

moment
→ momentum
→ to gain momentum
In most mechanics books, moment
and torque are used
synonymously

A

das Momentum, Impuls
→ Schwung
→ in Gang, Schwung kommen

24
Q

to occur
If tensile forces are too great,
rupture will occur

A

auftreten, entstehen, eintreten

25
to resist sth → resistance Bridges need to resist corrosive effects and damage from heavy loads.
widerstehen, aushalten → Widerstand
26
resultant → resultant (force) If one has two forces acting against each other, one subtracts the one force from the other to receive the resultant (force).
Resultante, Resultierende → resultierende Kraf
27
rupture → to rupture Tensile strength is the ability to withstand the weight of a load without rupture occurring
(Ab)bruch, Reißstelle → (ab)reißen, brechen
28
shear force → shear strength Scissors use shear forces to cut paper and other materials. Shear strength is the maximum shear stress that can be sustained before rupture
Scherkraft/Querkraft → Scherfestigkeit
29
strain, stress → to strain sth, to stress sth Whereas stress is the effect of a force on a component, strain is the deformation resulting from it
Belastung, Spannung → etw. belasten, beanspruchen
30
to sustain Cables have to sustain great forces
aufrechterhalten, ertragen
31
tension → tensile (strength) Tension is a pulling force which acts along the length of a component
Federkraft, Spannung, Zugkraft → Zug-(festigkeit)
31
torque Torque is the tendency of a force to rotate an object about an axis, fulcrum, or pivot.
Drehkraft, Drehmoment
32
torsion, torque → torsional (stress) Torsion is a twisting force

33
to wear, wore, worn → wear (and tear) [weə, teə] Wear and tear is damage that naturally occurs as materials age.
abnutzen, auch: tragen → Abnutzung, Verschleiß(erscheinung)
34
weight → to weigh In the physical sciences, the weight of an object is the magnitude of the force that must be applied to an object in order to support it in a gravitational field.
Gewicht → wiegen
35
to withstand (to sth) The ability to withstand tensile loads without rupture is called tensile strength.
etw. aushalten, standhalten, widerstehen
