Question 1

Consider the following statements:

Statement 1: The flexural stresses generated due to bending moment will be maximum at the centroid of the cross section

Statement 2: Neutral axis passes through centroid of the cross section.

Question 2

The maximum stress generated in the rope of diameter 25 mm passing over a pulley of diameter 400 mm. The modulus of elasticity of rope is 1.5 ×104 Mpa.

Question 3

A beam subjected to pure bending is loaded such that a compressive stress of 150 MPa is generated at a distance of 250 mm from neutral axis. If the modulus of elasticity of material is 200 GPa the radius of curvature of the beam will be

Question 4

A simply supported inverted beam of triangular cross section having base width 300 mm and height 450 mm is subjected to a bending moment of 50 kNm. The stresses in extreme tensile fiber is

Question 5

A cantilever beam of square cross section having depth 600 mm and span 8 m is subjected to a uniformly distributed load of magnitude 8.25 kN/m2. The stress generated at a distance equal to 2m from the free end and at a depth of 50 mm from NA will be

Question 6

A rectangular beam 300 × 600 mm cross section is subjected to bending moment of 50 kNm. The tension force generated in the beam is
