Forces in y-direction: [ R_y = W = 200 , N ]
Ignore friction at the hinge.
Then equilibrium: Horizontal: ( R\cos\alpha = T ), Vertical: ( R\sin\alpha = W = 200 ) N. Forces in y-direction: [ R_y = W =
Also, moment equilibrium (or concurrency) gives: The line of ( R ) must pass through I. ( R_y = R \sin(\alpha) )
But ( R_x = R \cos(\alpha) ), ( R_y = R \sin(\alpha) ), where ( \alpha ) = angle of ( R ) with horizontal. Forces in y-direction: [ R_y = W =
Forces in x-direction: [ R_x = T \quad (\textsince R \text has a horizontal component toward the right) ]
