Mikes Notes 3.1 question 25

Postby Ferdox » Wed Jul 05, 2017 10:09 am

NCARB 3.1 Practice Exam No.25
Can anyone explain why in Mike's notes he divides 4000 by 2. I assume the 4000 is from the loads 1000 ibs that are 4 ft from R1 but why the division by 2?
An explanation will be appreciated.

Because R1 carries 1/2 the total load.
As he tells you, "The loads are symmetrical and the reactions are equal".
