trying to resolve for Na and Nb which are reaction forces..

Sum forces x = m.a

0.25Na = 2200 x acc

Sum Forces y = 0

Na + Nb - 2200*9.81=0

Sum Moments (g) = 0

-Na(1.2)-0.25Na(0.25) + Nb(0.8) = 0

Could you show me the steps as Ive not got a clue how to deal with the unresolved moment equation simultaneously! cheers

Question

trying to resolve for Na and Nb which are reaction forces..

Sum forces x = m.a

0.25Na = 2200 x acc

Sum Forces y = 0

Na + Nb - 2200*9.81=0

Sum Moments (g) = 0

-Na(1.2)-0.25Na(0.25) + Nb(0.8) = 0

nincompoop · Answer

N would be? Normal force?

anonymous · Answer

can you give more information?

As far as summing the moments about g, there should only be 1 value for Na in the equation, not two, because you resolved the Na force into x and y components. here is what your moment equation looks like:
|dw:1384556755450:dw|
