W Shape

Solution to Problem 533 | Economic Sections

Problem 533
A beam simply supported on a 36-ft span carries a uniformly distributed load of 2000 lb/ft over the middle 18 ft. Using an allowable stress of 20 ksi, determine the lightest suitable W shape beam. What is the actual maximum stress in the selected beam?
 

Solution to Problem 530 | Economic Sections

Problem 530
Repeat Prob. 529 if the distributed load is 12 kN/m and the length of the beam is 8 m.

Solution to Problem 529 | Economic Sections

Problem 529
A 10-m beam simply supported at the ends carries a uniformly distributed load of 16 kN/m over its entire length. What is the lightest W shape beam that will not exceed a flexural stress of 120 MPa? What is the actual maximum stress in the beam selected?
