Which of the following deals with forces at rest?

static

Which of the following forces determines whether a body will be at rest or in motion.

resultant

Energy by virtue of velocity.

kinetic

Within proportional limit, the stress is directly proportional to strain.

Hooke’s Law

The ratio of lateral strain to longitudinal strain.

Poisson’s ratio

Within elastic range, the slope of the straight line portion of the stress-strain curve.

Young’s Modulus

The portion of the stress-strain curve beyond which the stress is no longer proportional to the strain?

Proportional limit

Materials having the same composition at any point are termed as:

Homogenous

Material property which enables it to under large permanent strains before failure?

Ductility

Forces generated by a bodies in motion?

dynamic

A time-dependent prestress loss in pretensioned concrete.

relaxation

Tendons are stressed before concrete is poured.

pre-tensioning

Tendons are stressed after concrete has hardened.

post-tensioning

The ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed.

elasticity

The ability of the material to deform under tensile stress.

ductility

The ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading.

resilience

The ability of a material to absorb energy and plastically deform without fracturing.

toughness

A material having the same strength at any point.

homogenous

The material composition is the same but its mechanical properties are different in every direction.

orthotropic material

Refers to the tendency of solid materials to return to their original shape after being forces are applied on them. When the forces are removed, the object will return to its initial shape and size.

elasticity

Refers to the stress at which a material begins to deform plastically.

yielding

The ability of the material to absorb energy in the plastic range.

toughness

The ability of the material to absorb energy in the elastic range.

resillience

The term which refers to the ability of a material to deform in the plastic range without breaking.

ductility

It is the point through which the resultant of the resistance to the applied lateral force acts.

center of rigidity

The point on a structure where the resultant vertical force acts.

center of mass

The distance between the center of mass and center of rigidity.

eccentricity

yielding

The ability of the material to deform in plastic range without breaking.

toughness

The greatest stress that can be applied to an elastic body without causing permanent deformation.

elastic limit

What will develop if the center of mass and center of rigidity of a structure does not coincide?

torsional shear stress

A building which has a floor which is less than 70% as stiff as the floor immediately above it, or less than 80% as stiff as the average stiffness of the three floors above it

soft storey

Refers to the lateral displacement of one level relative to the other level above or below.

storey drift

Which of the following best refers to the rigidity of a structure.

reciprocal of deflection

Which of the following best describes liquefaction?

sudden drop of shear strength

The point through which the resultant of the resistance to the applied lateral force aces.

center of rigidity

The point on a structure through which the applied seismic force acts.

center of mass

Refers to the flexibility of a structure.

reciprocal of stiffness

A property of a material which it has the same composition at every point but the elastic property may not be same in all directions.

isotropic

focal depth

Seismometer measures?

components of ground motion

A Richter Scale measures ________ of an earthquake.

magnitude

A material condition that causes it to deform permanently even due to slight increase of stress.

yielding

Fracture caused when a material is subjected to repeated cycles of stress or strain.

fatigue

When a material is loaded over a long period, it causes it to deform continuously until fracture.

creep

Refers to the lateral displacement of one level relative to the level above or below.

storey drift

Occurs when the structure's center of mass does not coincide with its center of rigidity.
