If the roller at A and the pin at B can support a load
up to 4 kN and 8 kN, respectively, determine the maximum
intensity of the distributed load w, measured in kN/m, so
that failure of the supports does not occur.
Even if the force at A wasn't calculated correctly, this video still was of tremendous help.
Reaction A is not perpendicular to line AB, break A into x and y components and you get exactly 2.67kN/m given by solution manual.
Sir you did not do the A part correct. A is perpendicular to the bent part of the beam NOT AB
This is actually incorrect. The distance you found is NOT the perpendicular distance. If you do the calculations correctly, the perpendicular distance is 3+4cos30. Since this number and the 6.77 achieved in the video are so close, your answer will only be slightly off, but is still incorrect if you use this method.
that line AB cannot be perpendicular to Force A unless if you talking about a third dimension
from -Fx2+Ax6.77=0 how do you get this equation? I dont get it. A force is not perpendicular to C=6.77. this is way too wrong
If you just extend FA out then the perpendicular distance from FA to B would be 3 + 4cos30. Then counter clock positive ΣMB = FW(2) - FA*(3+4cos30) = 0
to find the perpendicular distance to calculate the moment, you must [3/cos(30)] + 4...lets say that =a.....next, to find the distance, distance=(a) * cos(30) so now you have the perpendicular distance to the force so m=F*distance

this is correct, even according solution manual
you got the wrong answer
EXCELLENT =THANK U SIR
