STREMA TERMS

Midterm Exam

Bending Structures

Some of the most commonly used structures such as beams, rigid frames, slabs, and plates can be classified as

tension structures

trusses

bending structures

shear structures

Normal Force

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

bending force

torque

Tensile Stress

If the force is going to pull the material, the stress is said to be

shear stress

tensile stress

compressive stress

bearing stress

compressive stress

a concrete column supports the weight of building. what type of stress mainly acts on it?

shear stress

tensile stress

compressive stress

torsional stress

original cross-sectional area

tensile strength of a material is obtained by dividing the maximum load during the test by the

area at the time of fracture

original cross-sectional area

average of a and b

none of the above

both supports share equally

a simply supported beam carries a centered load. how are the reactions distributed?

left support carries all load

right support carries all load

both supports share equally

depends on beam material

along the cable

a cable attached to a structural member can exert a force that acts:

perpendicular to the cable

along the cable

vertically upward only

horizontally only

perpendicular to the inclined surface

a roller support is placed on an inclined surface. in which direction does its reaction normally act?

parallel to the inclined surface

perpendicular to the inclined surface

horizontally

vertically

fixed support

a balcony beam is rigidly embedded into a reinforced concrete wall. the connection prevents the beam from translating and rotating. which idealized support should be used in the structural analysis?

roller

pin

cable

fixed support

tension

a signboard supported by a cable attached from the top of the sign to the ground. during strong wind, the cable becomes tight and helps prevent the sign from falling. what type of force does the cable exert?

compression

tension

bending

torsion
