howdy - hope dis aint 2 late!! [its 2003 q 17]

A=4(pie)d*2
--------------
4


Stress=Load
-------
Area

450x10*6 =5x70x10*3
--------------
(pie)d*2

d*2 = 5x70x10*3
-------------------
450x10*6x(pie)

d*2 = 2.476x10*-4

therefore

D = 0.016m
D = 16mm

b.t.w - (*) denotes "to the power of"

for example:

4*7 = 4 to the power of 7

- hope this helps - GOOD LUCK!!!!!!!
