Structure an assemblage of number of resistant bodies having no relative motion between them.
STRUCTURE
• Structure an assemblage
of number of resistant bodies having no relative motion between them.
• They are meant for
carrying loads having straining action.
• The resistant bodies
which constitute a structure are known as its members. Fig. 1.5 shows sample
structure having three members 1, 2 and 3.
• No relative motion is
possible between these members. However due to applied forces or loads, the
structure is subjected to straining action.
• Practical examples:
Roof trusses, bridges, buildings, machine frames, etc.
1. Machine Vs Structure
• Machine is an assemblage
of links or mechanisms which are used to transmit both the required motion and
forces.
• The comparison between machine and
structure is given in Table 1.2.
