A prismatic beam having circular cross section is subjected to maximum bending stresses of magnitude 30 N/mm2 due to which it bends into an arc of radius 500m. The diameter of the beam if the modulus of elasticity is 2 ×105 Mpa.
Question 2
Consider the following statements:
Statement 1:Moment of inertia of I section is greater than rectangular section for the same cross sectional area.
