Homework Statement: Write Boolean expression for ladder diagram. X are switched input, M represents internal relay contact and Y000 is a motor contact

Relevant Equations: """"""""""""""""""""""""""""_____"""_____
F = X000 . ( M1 + ( M2 . X002 ) . X003

Hi,
I wonder if I am on the right way
"""""""""""""""""""""""""""______"""______
F = X000 . ( M1 + ( M2 . X002 ) . X003

Looks good to me.

Cheers,

p.s. Glad you included the attachment, trying to represent it graphically in text is tough on this site with their proportional font!

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
