a) An X mm rod length with Y mm diameter is put under tension load gradually in order to complete a tensile test. The load and the elongation during the experimental session is tabulated in Table 1. Given that X mm rod length value is equivalent to the 3rd to 5th number from your own matric number. Example: For matric number of 1812019, X mm rod length value is equivalent to 120 mm. As for Y mm rod diameter value, consider the last number from your own matric number. Example: For matric number of 1812019, Y mm rod diameter value is equivalent to 9 mm. If your last matric number is 0, take Y mm value as 9 mm. By plotting the stress-strain diagram of the data set using Microsoft Excel,

Transcribed Image Text:a) An X mm rod length with Y mm diameter is put under tension load gradually in
order to complete a tensile test. The load and the elongation during the experimental
session is tabulated in Table 1. Given that X mm rod length value is equivalent to
the 3rd to 5th number from your own matric number. Example: For matric number
of 1812019, X mm rod length value is equivalent to 120 mm. As for Y mm rod
diameter value, consider the last number from your own matric number.
Example: For matric number of 1812019, Y mm rod diameter value is equivalent to
9 mm. If your last matric number is 0, take Y mm value as 9 mm. By plotting
the stress-strain diagram of the data set using Microsoft Excel,
