Homework Statement



If the load on the uniform beam shown below is moved to the left, how do the tension force T and the magnitude of the vertical force Fv exerted by the wall on the hinge change?

The answer is A

Homework Equations


torque = Fdsin(theta)

The Attempt at a Solution


My equation was Tsinx = fd. I understand when the object is moved to the left the distance decreases, and the angle decreases, but I don't understand how the vertical force increases exerted by the wallAlso for the 2nd question ( the ladder one) why is the answer B? What I thought was Fgdcos theta = FN2(d)(cos theta) + FN1(d)(cos theta), so when the distance for FN1 increases wouldn't the force increase too?

I cannot understand your notation. Is this a force equation or a moment equation? What is Fgd? Is FN2(d) the force FN2 as a function of d, the distance up the ladder, or is it a force multiplied by a distance?
(You will need to consider moments to answer the question.)

Oh I meant Fg(d) and it's for the torque equation
