For this you need the E and the I of the beam section. That is the Youngs Modulus of the beam material and the second moment of area that controls bending in the vertical plane. Then I would look up the case of a simply supported beam with a point force in Roark's Formulas for Stress and...

Its also worth noting that you need to know the mass of the wedge to calculate the horizontal (and vertical) accelerations of the wedge and block. Mass times acceleration of one is equal and opposite to mass times acceleration of the other.

There are no moment reactions, only force reactions. Therefore the pivot pin is subjected to a vertical shear force only. You can take moments either about point A or Point C because the sum of the moments at these positions is zero.

Hi, My name is Gordon Mutten. I have been a stress engineer for 40 years working on aircraft, spacecraft , and several other products involving metals and composites etc. I would like to offer my help with simple stress analysis questions. I am soon to start a website for this subject so I...

The reactions are both 250 lbs (not lbs in). The angle makes no difference as long as the symmetry stays the same because all forces are assumed vertical.
