Hello everyone, i nearly finished the problem but I get the wrong moment, so i would like to know what I missed. See the image in the attachment.
So the questions is as a following: Replace all the 4 forces and the moment in the figure with a resultant R and a resulting moment M in Point 0. Also give direction of R in comparison to the x axis.
The correct answers should be R = 148,3 N, Angle = 63,2 and Moment : 273,3 N
I will now present my solution:
Rx = 4060cos45 + 80 cos30 = 66,8556
Ry = 50+60sin45+80sin30 = 132,426
R = SQRT((66,8556^2)+(132,426^2)) = 148,345
tan alpha = O/A = 132,426/66,8556 = 63,213 after using inverse of tan.
Now to my problem where I am stuck Is calculating the moments ok lets do it
Mo (with right hand rule) : 14050*542,464*7+42,4264*4=
140250296,985+169,706 =  237,279
This is where I need your help. What did I do wrong? Did i miss something?
Could someone tell me and show me analytically how it should be solved?
Thank you.
