Question 2

Which of the following best describes the condition of a 'statically determinate' structure?

Accepted Answer

Reactions and internal forces can be found using equilibrium equations alone

Answer

The structure has more unknowns than equilibrium equations

Answer

The structure cannot be analyzed without material properties

Answer

The structure has redundant members that carry no load

Question 3

In reinforced concrete design, the term 'balanced section' refers to:

Accepted Answer

A section where concrete crushing and steel yielding occur simultaneously

Answer

A section with equal amounts of tension and compression steel

Answer

A section where the neutral axis is at mid-depth

Answer

A section with minimum reinforcement ratio

Question 4

What is the slenderness ratio of a column, and which value typically indicates a 'long' (slender) column?

Accepted Answer

KL/r; values greater than 120 are typically considered long columns

Answer

L/b; values greater than 50 indicate a long column

Answer

KL/d; values greater than 30 indicate a long column

Answer

L/r; values less than 20 indicate a long column
