The Mechanics of Materials laboratory is the place where students are initiated to
techniques and instrumentation for measuring strain, stress and fatigue life testing.
A range of experiments are designed to measure strains on the surface of components or
specimen using A 10 Channel Module with embedded Strain Gage Conditioner, Digital Readout
and Power Supply. The measured strains enable the computation of the mechanical stresses
taking into account the material properties such as modulus of elasticity and Poisson's
ratio. Other equipment available to students include the Wilson Rockwell for hardness
test, Combined Bending and Torsion Apparatus with Dial Indicator to monitor deflections,
Rotating Bending Fatigue Machine for fatigue test, and P-3500 Strain Indicator to
familiarize students with Wheatstone Bridge Circuit (Quarter bridge, half bridge and full
bridge). Students are also introduced to installing strain gage with M-Bond 200 and AE-10
Adhesive Systems. This laboratory is projected to expand in order to include experiments
using photoelasticity, interferometry, and digital image correlation. For more
