Question

Attached are two images, one of the homework problems in which we must replace some of the numbers in the problem. Here are the problems and what we are suppose to replace within the given problems.

F4-37: change the right 1.5m to 2.5m, F4-38: change 8ft to 7ft, F4-39: change 6m to 8m.

The professors wants us to solve the problems accordingly: REPLACE THE DISTRIBUTED FORCES WITH PROPERLY LOCATED CONCENTRATED FORCES. DO NOT REPLACE THE CONCENTRATED FORCES WITH A SINGLE CONCENTRATED FORCE. SPECIFY THE LOCATIONS OF CONCENTRATED FORCES USING X -COORDINATES WITH ORIGINS AT THE LEFT END OF EACH BEAM.

I am not sure how to solve this the way the teacher is asking for can someone please help me with all three?

Explanation / Answer

F4-39

Fr=1/2(8)(3)-1/2(8)(8)

Fr=-12-32=-44 kN or 44 kN down ans.

Moment around A

-27d=1/2(8)(3)(1)-1/2(8)(8)(2)

-27d= 12-256

-27d=-244

d= 9.04m ans.
