8.2. Flexural Deformations

Try these first

1. 1.

   What is the definition of curvature in relation to beams?

   Hint

   Think about how much a curve bends.

2. 2.

   What is the common limit for beam deflection?

   Hint

   Use the ratio related to the load span.

3. 3.

   What is the typical maximum allowable deflection for beams under load?

   • 1/200
   • 1/360
   • 1/480

   Hint

   Remember the standard ratios used in structural engineering.

4. 4.

   True or False: The curvature of a beam is independent of the applied moment.

   • True
   • False

   Hint

   Consider how forces create curvature.

5. 5.

   A wooden beam is 10 ft long and carries a central load of 600 lbs. Calculate the maximum deflection using appropriate flexural formulas.

   Hint

   Remember the necessary constants for dimensions and material properties.

6. 6.

   Given a beam made of steel with a modulus of elasticity of 29,000 ksi. If the moment of inertia is 200 in^4, determine how much it deflects with a central load of 3000 lbs.

   Hint

   Make sure to convert units appropriately.
