Equilibrium
I’m having trouble understanding this question.
A rigid uniform beam (0.5m in length) of weight 200N is hinged to a wall and held horizontally by a string 40 degrees to the horizontal. a) Calculate the tension in the string. b) The horizontal contact force of the wall on the hinge.
I’m assuming I have to use moments?
I think the weight would provide a clockwise moment
m = Fs
= 200N x 0.25 (because I think the weight will act in the centre of the beam?)
This will equal the anticlockwise moment provides by the tension in the string.
For this would I work out the vertical component? I’m lost on what I have to do to be honest, any help would be appreciated.
