The value of the outside diameter d for a steel pipe.
Answer to Problem 11.9.18P
The value of the outside diameter d for a steel pipe is 99 mm.
Explanation of Solution
Given Information:
The length of the column, L = 3.5 m
The allowable load, P = 130 kN
The value of the young modulus, E = 200 GPa
The value of maximum stress, sy = 275 MPa
The thickness of the steel pipe, t = d/20
Here ,d is the outside diameter of the steel pipe.
Concept Used:
Lc = critical length of column in ft.
Then we choose different diameters d and calculate till the value of Pallow =P
Calculation:
Here,
Lc= critical length of column in mm.
Select various values of d until Pallow= P.
For d1=97mm,
For d2 = 98mm,
For d3= 99mm.
Conclusion:
The value of the outside diameter d for a steel pipe is 99 mm .
