AN m$-$c$-$K SUSTEM HAS THE FOLOWING tEST RESULTS:

i$)$ WHEN AN ADDITIONAC $10"$ WEIGHT IS ADDED TOTHEMASS,

THE SYSTEM DEFLECTS AN ADDITIONAR $0\mathrm{.}2$ inches $({0\mathrm{.}2}^{\text{'}\text{'}})$

ii$)$ WhEN THE SYSTEM IS DISPLACED FROM REST L Released,

tTHE SUbsequent Vibration Diminishes FrOMAN AMpUTUDe

of ${2\mathrm{.}35}^{\text{'}1}$ TO ${1\mathrm{.}21}^{\text{'}\text{'}}$ in ExActly $2$ cycles

iii$)$ THE MEASURED TIME FrOM ONE PEAK TO ANOTHER

is $1\mathrm{.}5$

DETERMINE THE SELF WEIGHT OF THE SYSTEM.
