A beam is subjected to a moment of 50 kNm. If the section modulus is 10 cm^3, what is the bending stress in the beam?

A beam is subjected to a moment of 50 kNm. If the section modulus is 10 cm^3, what is the bending stress in the beam?

Step 1: Understand the formula for bending stress, which is σ = M/Z.
Step 2: Identify the values given in the question: M (moment) = 50 kNm and Z (section modulus) = 10 cm^3.
Step 3: Convert the moment from kNm to Nm: 50 kNm = 50,000 Nm.
Step 4: Convert the section modulus from cm^3 to m^3: 10 cm^3 = 10 / 1,000,000 m^3 = 0.00001 m^3.
Step 5: Substitute the values into the formula: σ = 50,000 Nm / 0.00001 m^3.
Step 6: Calculate the bending stress: σ = 5,000,000 Pa or 5 MPa.
