Question

Q1. For bending equation to be valid, radius of curvature of the Beam after bending should be ? (1). Equal to its transverse dimension (2). Infinity (3). Very large compared to its transverse dimension (4). Double it's transverse dimension

Answer 1

Answer:

ans (3)

Explanation:

very large compared to its transverse dimension

Answer 2

Answer:

(3). Very large compared to its transverse dimension.

Explanation:

As per the assumptions of bending of the beam the radius of curvature of the beam after bending should be very large compared to its transverse dimensions means the deflections should be very less. So option 3 is correct.

Stress: Stress is the ratio of the load or force to the cross-sectional area of the material to which the load is applied.The standard unit of measure for stress is N/m2.The stress is directly proportional to the load and here the load is in terms of bending.

Bending: Bending is a process by which metal can be deformed by plastically deforming the material and changing its shape. The surface area of the material does not change much. Bending is deformation about one axis.
