Module 5: Analysis of Structure Flashcards
consist exclusively of straight members connected at joints
located at the ends of each member
trusses
is a structure composed of
slender members joined together at
their end points
trusses
When we need to find the force in only a few members of a truss, we can analyze the truss
using the?
method of sections
The members
commonly used in construction consist of ______________ or _________________
wooden struts, metal
bars
two-force members
trusses
the forces of action and reaction between two bodies in contact have the same?
- magnitude
- line of action
- opposite sense
5 typical trusses
- pratt
- howe
- fink
- warren
- baltimore
are two types of structures which are often
composed of pin-connected multi-force members.
frames and machines
always contain at least one multi-force member, (not
directed along the member.)
frames
can also be used to
“cut” or section the members of an entire
truss.
method of sections
designed to support load
trusses
structures containing moving parts
machines
designed to transmit and modify forces
machines
3 broad engineering structure
- trusses
- frames
- machines
both of these are usually stationary and fully constrained structures
trusses and frames
these lie in a single plane and are often used to support roofs and bridges.
planar trusses
both of these are designed to support loads
trusses and frames
both of these always contain at least one multi-force member
frames and machines
usually stationary and fully constrained structures
trusses
This method is based on the fact that if the entire truss is in equilibrium, then each
of its joints is also in equilibrium.
