Hello everyone,
Thank you for your sharing information, I think I found the right answer, but I am not really sure why it is right.
net torque = (75)(9.8)3sin30 + (10)(9.8)2.5sin30 - 4.33F3 = 0
1102.5 + 122.5 - 4.33F3 = 0
F3 = 282.9 N
The part I don't understand is (4.33)(F3). why does r = 4.33? That would mean that r just goes straight down and the force must be Horizontal. the other two r's are horizontal, and the force goes straight down.
Thanks and regards
Andy Charles
