The elastic limit of brass is 379 MPa . ...

The elastic limit of brass is 379 MPa . What should be the minimum diameter of a brass rod if it is to support a 400 N load without exceeding its elastic limit ?

Text Solution

Verified by Experts

Stress `=F/A=(400xx4)/(pid^(2))=379xx10^(6)N//m^(2)`
`impliesd^(2)=(400xx4)/(379xx10^(6)pi)`
`d=1.15 mm`
