Can you help me understand this Mathematics question?

Structural systems assignment 3

solve problems and show work

see attached please

Problem 1

5:34 l LTE Scanned Documents Done 1 of 3 PROBLEM 1 PRACTICAL TRUSS EXAMPLE A. FIND A STRUCTURAL TRUSS (INDOORS OR OUTDOORS) AND TAKE A PICTURE OF IT B. DRAW THE TRUSS CROSS SECTION (IF IT IS A 3d TRUSS THEN JUST DRAW ONE SI OF THE TRUSS sO THAT WE CAN ANALYZE IT). MAKE ASSUMPTIONS FOR THE RELATIVE DIMENSIONS c WHERE ARE THE LOADS BEING APPLIED? ADD SOME LOADS TO THE PICTURE WHERE YOU WOULD EXPECT THEM TO BE LOCATED (MAKE SURE TO DRAW IN THE CORRECT DIRECTION!) ORAW THE TRUSS AGAIN AND APPLY A SINGLE POINT LOAD DOWNWARDS IN THE MIDDLE OF THE TRUSS. LABEL WHETHER YOU’D EXPECT THE MEMBERS TO BE IN TENSION OR COMPRESSION. (OR COLOR CODE BY HIGHLIGHTING THE TENSION MEMBERS IN BLUE AND THE COMPRESSION MEMBERS IN RED. E IS THE TRIUSS AS YOU HAVE DRAWN IT DETERMINATE OR INDETERMINATE?

Problem 2

A) USE THE METHOD OF JOINTS TO SOLVE FOR THE FORCES IN THE MEMBERS 1, 2, 3, AND 4 INDICATED BELOW (LABEL WHETHER TENSION OR CCMPRESSION)

B) USE THE METHOD OF SECTIONS TO SOLVE FOR THE FORCES IN THE MEMBERS 1 AND 2 INDICATED BELOWN (LABEL WHETHER TENSION OR COMPRESSION)

Problem 3

FOR THE TRUSS AND LOADS BELOW SOLVE FOR
A FIND THE REACTIONS AT A and B
B. FIND THE FORCE IN MEMBER 1
C. FIND THE FORCE IN MEMIER 2
D, FIND THE FORCE IN MEMBER 3
(MARE SURE TO INDICATE WHETHER THE MEMBERS ARE INTENSION OR COMPRESSION!)
