Quiz #4 • Today Exam #2 • Friday, October 10 • Last day to drop without a grade reported is: Tuesday, October 14 Lecture 16
Last Lecture • Centroids of composite sections QUESTIONS ????? Today • Section 4.6 - Distributed Loads Lecture 16
Distributed Loads • Distributed loads on beams • Application of equivalent load • Example Lecture 16
P w(x) x dx L Beams Beams can be loaded by a point load or a distributed load Replace the distributed load with an equivalent concentrated force. The equivalent force is the sum of all the forces. Lecture 16
w(x) xc W L Equivalent Load Location The equivalent load is placed at the centroid of the distributed load. To find reaction loads: replace distributed load with equivalent load at centroid Lecture 16
