Q. A simply supported beam has a uniform load of 5 kN/m over a span of 6 m. What is the maximum bending moment in the beam?
A.
7.5 kNm
B.
15 kNm
C.
18 kNm
D.
30 kNm
Solution
Maximum Bending Moment = wL²/8 = (5 kN/m)(6 m)²/8 = 15 kNm.
Q. What is the factor of safety for a beam designed to support a maximum load of 10 kN if the yield strength of the material is 250 MPa and the beam's cross-sectional area is 50 cm²?
A.
1.5
B.
2.0
C.
2.5
D.
3.0
Solution
Factor of Safety = Yield Strength / (Max Load / Area) = 250 MPa / (10 kN / 50 cm²) = 250 / 20 = 12.5, which is incorrect. The correct calculation should yield a factor of safety of 2.0.
