- Q1: What do you know about deflection?Ans: The displacement of a point from its original position is called deflection. OR
The vertical distance between the displacement point and original position is called deflection.
It is denoted by “y” - Q2: Define slope of beam.Ans: The angle between the original position of the beam and its deflection point is called slope of the beam.
It is denoted by θ. - Q3: Define stiffness of beam.Ans: The resistance of a beam against deflection is called stiffness.
- Q4: Define elastic curve.Ans: When load is applied on the beam, the beam deflects and bends in the shape of a curve, this curve is called elastic curve.
- Q5: What is Mohr’s Theorem I?Ans: Mohr's theorem I states:
“The change of slope between any two points on an elastic curve is equal to the net area of the Bending Moment diagram of these points divided by EI”. - Q6: What is Mohr’s Theorem II?Ans: Mohr's theorem II states:
“The interrupt vertical reference line of tangents at any points on an elastic curve is equal to the moment of the BM diagram between these points about the reference line divided by EI”. - Q7: Define Flexural Rigidity.Ans: The product of Young’s Modulus and Moment of Inertia is called Flexural Rigidity.
Flexural Rigidity = EI
