I'm almost sure that all of u had once ride this 'horse-ride' thing in a playground..If u are asked to design this spring that it can hold different weight of children and at the same time allow the kids to feel the bounce... what kind of spring features will u choose???
The features should be based on the following aspect ;
i. its spring constant value
ii. diameter
iii. coil thickness
iv. type of metal
Give reason for each features that u've recommended.
U can give your version of answers in a comment section. Lets discuss it!!!

no idea, sir..
pls help us!!mne le tau soaln ni msuk exam..pls sir!!
ok 1st u kena tau relate spring constant (k) dgn stiffness..
lagi besar spring constant, lagi keras spring tu....
dari segi thikness plak, lagi tebal spring lagi keras..so dlm kes ni kita guna yg tebal sbb dia boleh support variety range of children's weight...
dari segi diameter, lagi besar diameter kekerasan spring akan menurun, so dia boleh bounce...
type of metal should be high in strength & low rate of rusting..so it can last longer
