Question

Assume that a max stress is to be the limiting factor in selecting a box-beam having a span length of 154mm. The Aluminum beam with a yield strength of 276MPa is fixed at one end and loaded at the free end by 1kN. Determine the minimum Section Modulus in mm^3. Use a safety factor of 2.6. 

Expert Solution
Step 1: Mention the given data.

Span length, L equals 154 space mm

Yield strength, sigma subscript y equals 276 space MPa

Load at free end, w equals 1 space kN

Safety factor, F S equals 2.6

To find: Minimum section modulus.
