2E4: SOLIDS & STRUCTURES
lids & Structures
What does the module cover?
The module covers two fundamental concepts:
Strength of Materials
Theory of Structures
(covered by Alan O’Connor)
It is a must that you
a book on the subject,
Mechanics of Materials/
Strength of Materials/
Mechanics of Solids
Buy it first or second hand
or download it
•Mechanics of Materials by A. C.
or why things don’t fall down by JE
•Strength of Materials by S.
Written Exam (85%)
Two Laboratory Experiments (5% each)
10 tutorials (5 BG and 5 AOC)
Attendance is worth 50% of tutorial marks.
Students must attend the tutorial sessions during weeks 2
to 6, inclusive, and weeks 8 to 12:
Groups A and B: 9:00am to 10:00am in the Drawing Office,
Groups C and D: 10:00am to 11:00am in the Drawing
Office, Museum Building.
Load will be applied on a simply
The beam will bend with compression at top and tension
Deflection will be calculated using dial gauges.
The strain will be measured using strain gauges.
Stress will be calculated from the strain measurements.
Strain and deflection gauges will be used.
Buckling of a Strut
Buckling is a large deformation produced under
compressive load in a direction or plane normal to the
direction of application of the load.
Four different end conditions show four different shapes of
Load bars with different end conditions in the loading
frames and observe the different shapes and critical load:
1) Effect of end condition:
Draw the first mode shape for the four different end
conditions in the small loading frame.
Measure the effective length for each end condition.
1I) Effect of length
Measure the critical load for two bars having different
length in the big loading frame.
Measure the width and depth of the section of the bars
Calculate the radius of gyration of the section of the bars.
