Truss design

Picture
For this project we had to make 3 different trusses. The first 2 trusses were given and the third truss we had to make. We made the trusses and then tested how much force they could take before breaking. We had about a week to work on this project.

Challenges

Truss calculations for truss 1

2J=M+R
3 Joints, 3 Members, 1 Roller Joint, 1 Pin Joint
2*3=3+3
6=6=Statically determinate
RAy = 22.255N
RAx = 0N
RCy = 22.255N
AB,CB = 45.91N
W=.014715N F=44.51N
Efficiency=3024.8

Truss calculations for truss 2

2J=M+R
5 Joints, 6 Members, 2 Pin Joint
2*5=6+4
10=10=Statically determinate
W=.01962N F=39.3N 
Efficiency=2003.1

our Own truss

2J=M+R
6 Joints, 7 Members, 2 Pin Joint, 1 Roller Pin
2*6=7+5
12=12=Statically determinate
W=.024525N F=21.23N 
Efficiency=865.6

Final sketch

Picture
When I went to test our own truss I made a mistake by breaking the truss on the middle instead of a joint. I would like to try to make my truss again and see how much force it can take on a joint. The truss very easily because I broke it on the member.
