Simple Stress - Axial/Normal Stress

Question 1

Is the branch of physics that considers the
action of forces on bodies or fluids that are both
at rest and in motion.

Answer 1

Mechanics

Question 2

Is the branch of engineering that applies the
principles of mechanics to any design that must take
into account the effect of forces.

Answer 2

Engineering Mechanics

Question 3

Is the
study of the internal effect of external forces
applied to structural member.

Answer 3

Strength of Materials or Mechanics of Deformable Bodies

Question 4

It includes stress,
strain, deformation deflection, torsion, flexure,
shear diagram, and moment diagram

Answer 4

Strength of Materials or Mechanics of Deformable Bodies

Question 5

This force acts
perpendicular to the area. It is developed
whenever the external loads tend to push or
pull on the two segments of the body

Answer 5

Normal Force (N)

Question 6

The _____ lies in
the plane of the area and it develop when the
external loads tend to cause the two
segments of the body to slide over one
another.

Answer 6

Shear Force (V)

Question 7

This effect
is developed when the external loads tend to
twist one segment of the body with respect to
the other about an axis perpendicular to the
area

Answer 7

Torsional Moment or Torque (T)

Question 8

Is caused by the external loads that tend to
bend the body about an axis lying within the
plane of the area.

Answer 8

Bending Moment (M)

Question 9

Is defined as the strength of a material per unit area
of unit strength. It is the force on a member divided by area,
which carries the force, formerly express in psi, now in N/mm2 or
MPa.

Answer 9

Stress

Question 10

Where P is the applied normal load in Newton and A is the
area in mm^2. The maximum stress in tension or compression
occurs over a section normal to the load.

Answer 10

𝝈 = 𝑷/𝑨

Question 11

Develops when a force is
applied perpendicular to the cross-sectional area of the material

Answer 11

Normal Stress

Question 12

Is developed if the
applied force is parallel to the
resisting area.

Answer 12

Shear Stress

Question 13

It is the contact pressure
between two bodies

Answer 13

Bearing Stress

Question 14

Is either tensile stress or compressive stress. Members
subject to pure tension (or tensile force) is under tensile stress,
while compression members (members subject to compressive
force) are under compressive stress.

Answer 14

Normal Stress

Question 15

will tend to shorten the
member

Answer 15

Compressive force

Question 16

will tend to
lengthen the member

Answer 16

Tension force
