ARCH 331 - Quiz 1 Questions And Answers With Verified Solutions 2025
concurrent force system - ✔✔all forces act through a single point
graphical truss analysis (or Maxwell's diagram) - ✔✔analysis using force polygons based on the joint
loads and angles of the truss analysis
structural system materials - ✔✔wood, steel, reinforced concrete, masonry and composite construction
cable force - ✔✔cables are in tension with the force in the direction of the geometry of the cable
(neglecting gravity)
special truss member configuration with two members - ✔✔Two members (or forces) in line have equal
forces. Two members out of line must have zero force in each.
coplanar force system - ✔✔all forces act in the same place
truss - ✔✔an assembly of shorter members which is used to span horizontally, and commonly is used for
large spans
parallelogram law - ✔✔the method applied to determine the resultant of two vectors by constructing
parallel lines
internal forces - ✔✔forces that are within bodies, or at connections between bodies
compression - ✔✔an action, or stress that shortens or pushes
moment of a force - ✔✔the vector quantity represented by the product of a force with the
perpendicular lever arm to some axis, or the tendency of a force to produce a rotation for a body
, pin connections - ✔✔connections between two or more bodies that only resist translation, and do not
resist rotation
external forces - ✔✔forces that are applied or act on bodies
light loads and structure type - ✔✔Surface forming elements appropriate. Joints or trusses at regular
intervals.
assumptions for analysis - ✔✔the truss members have force only running through the pins (axial forces)
and any bending is negligible
special truss member configurations with three members - ✔✔Three members (or forces) with two in
line have will have equal forces of the ones in line. The other must have zero force.
one-way systems - ✔✔characterized by elements that channel load in one direction only
parallel force system - ✔✔all forces are parallel
horizontal span to depth relationship - ✔✔The depth squared is related to the length. Increasing the
span will require more than a proportional depth increase.
static and friction - ✔✔the maximum friction force that is a magnitude based on the coefficient of static
friction and the normal of an object in contact with a material that will maintain equllibrium
number of levels in horizontal systems - ✔✔a classification system to describe how many horizontal
collectors are used, for example, joist with beams is a two-level system
live load - ✔✔In the general sense, any load that comes and goes with time. As a specific category of live
load, it generally refers to occupancy (people)
impact load - ✔✔a load from an impact which is significantly higher than the same load applied
gradually
concurrent force system - ✔✔all forces act through a single point
