Question 159
For a cantilever beam of length L continuous at the support and unrestrained against torsion at the support and free at the end, the effective length 'l' is equal to
Solution
Cantilever beams of projecting length L when unrestrained against torsion at the support and free at the end : $$l=3.0L$$
When partially restrained : $$l=2.0L$$
When restrained : $$l=L$$
