Strength of Materials
The width b and depth d of a beam cut from a wooden cylindrical log of 100 cm diameter for maximum strength are :
b = 57.73 cm d = 81.65 cm
b = 81.65 cm d = 57.73 cm
b = 50.00 cm d = 50.00 cm
b = 40.00 cm d = 80.00 cm
b = 30.00 cm d = 60.00 cm.
Correct Answer:
b = 57.73 cm d = 81.65 cm
