1. Define the Si prefixes and their values: G- 2. For the following calculations, properly convert the units to stress (force per area) P10.2 ksi Mpa 25 in Pa It 10., mmuf (100m)
Solution
1) K- kilo: 1000
M - Mega -1000000
G - Giga - 1000000000
2) a) 10.2/0.65 = 15.69 ksi
b) (40* 10^6 N.mm)(60 mm)/(8.64*10^6 mm4) = 277.7 MPa
c) (75*(2/12 ft))/(25/12^4 ft4) =10368 PSF
d) (150*10^3)*300/(10^7 *100*10^-6) = 45000 pa.
