How do I find deflection in this beam?

  • #1
How do I find deflection (displacement) in point C at the end of the beam? Answer is to be given in mm. There is a roller connection (only Fy) in B and an external pin in A (Fy and Fx).

As in all beam problems, first determine the reactions at A and B which put the loaded beam in equilibrium.

Once that is done, you can determine the deflection at C from first principles (if you like doing the math) or you can use software which analyzes beam problems.

To find the true deflection of the beam, you will need to know the modulus of elasticity (E) and the moment of inertia (I) of the beam.

See this attachment:

The deflection of your beam would be approximately equal to the sum of the deflections from case 1 and case 4. Your beam is not exactly fixed at point B so the deflection at C will only be approximate. Like I said earlier, in order to find the exact amount of deflection, you would have to analyze the beam from first principles.
