Solid Mechanics Concept Review Exam 1

Shear stress acting on the cross section of a beam is

Tangential to the cross section

Which of the following best describes normal stress in a member under axial loading?

The stress intensity acting perpendicular to a section cut normal to the axis.

In the context of a plane stress state, which of the following assumptions is typically made?

Stresses are assumed to act only within a single plane, and out-of-plane stresses are zero or negligible.

In a double shear connection, the internal shear force on each plane is:

Half of the applied load

Which of the following statements about bearing stress is correct?

It is defined as the average force intensity over the projected contact area.

Which of the following correctly explains the condition of shear stress equilibrium within a plane?

Adjacent shear stresses on the same plane must act toward each other or away from each other with equal magnitude.

What is shear modulus?

Ratio of shear stress to strain stress

What is bulk modulus?

Measure of resistance of a material to bulk compression.

Which of the following statements is wrong about Thermal Strain and Thermal Stresses?

Stresses develop in the structure as the temperature increases even if the structure is not restrained.

Which of the following statements is wrong about the poisson's ratio?

It is the negative ratio of longitudinal strain to lateral strain.

Which of the following stements is wrong about generalized Hooke's law?

Each stress component induces strain only in its respective direction and no strains in the other two directions

Which of the following statements is wrong about Statically Indeterminate Structures?

The number of internal and reaction forces is less than the available static equibrium equation.
