One notable fact you learned about elastic deformations is that:
1.when the applied stress is positive, the strain will be negative.
2.stress and strain have the same dimensions of force per unit area.
3.the permanent deformation is proportional to the applied stress.
4.when the applied stress is zero, the strain will be zero.
5.the permanent stress is proportional to the applied strain.

Please help me finding the answers for these Multiple choice
If material "A" stretches 20% when a very small tensile stress is applied and material "B" stretches 1% when the same tensile stress is applied the elastic modulus (intrinsic stiffness) is higher for material "A" than for material "B" the elastic modulus (intrinsic stiffness) is higher for material "B" than for material "A" this tells us nothing about intrinsic stiffness extensibility is higher for material "B" than for material "A"...

Cantilever Testing Procedure 1. Check dimensions of the bar stock aluminum. You should record the width and thickness with a caliper and then use the yardstick to measure the length of the bar to the table. Also record the distances to each of the sets of gages and the distance to the middle weight. The distances are fairly accurate so it is safe to round to the nearest whole inch, except for the distance from the free end of the...
