A truss that is pinned at one end and on rollers at the other will be statically
Question:
A truss that is pinned at one end and on rollers at the other will be statically determinate if it satisfies the following equation:
0 = 2j - m - 3
where j is the number of joints and m is the number of members. This is a quick way to check for static determinacy without drawing the FBDs. Apply this equation to:
a. Verify that the trusses in Exercises 7 through 12 are statically determinate.
b. Sketch three statically determinate truss bridges with the following numbers of members: (1) 11 members, (2) 15 members, and (3) 19 members.
