Math Mechanics Pt.3

Refers to the highest ordinate on the stress-strain diagram.

• rapture strength

• ultimate strength

• yield strength

• allowable strength

At highest or lowest point on the moment diagram.

• shear is maximum

• shear is zero

• shear is half the maximum

• shear is negative

For symmetrically loaded simple bam the maximum shear occurs at

• the midspan

• the support

• 1/3 from the support

• 1/4 from the support

For symmetrically loaded simple beam, the maximum moment occurs at

• the midspan

• the support

• 1/3 from the support

• 1/4 from the support

Poisson ratio is

• the ratio of the stress to strain

• the other term for slenderness ratio

• the other term for factor of safety

• the ratio of the unit lateral deformation to the unit longitudinal deformation

Which of the following is NOT a method of determining the bar force of a truss member.

• method of joints

• method of section

• method of virtual work

• maxwell diagram

The actual stress the material ahs when under load.

• allowable stress

• ultimate stress

• working stress

• factor of safety

The ratio of the volume stress to the volume strain is called

• young's modulus

• shear modulus

• bulk modulus

• hooke's law

A kind of stress that is caused by forces acting along or parallel to the area resisting the force.

• tensile stress

• bearing stress

• shearing stress

• tangential stress

Stress is proportional to strain. The constant of proportionality is called as Young's modulus. Who introduced this in 1807?

• Sean Young

• Neil Young

• James Young

• Thomas Young
