Two shafts will have equal strength, if
A. Diameter of both the shafts is same
B. Angle of twist of both the shafts is same
C. Material of both the shafts is same
D. Twisting moment of both the shafts is same
Answer: Option D
Solution (By Examveda Team)
Two shafts will have equal strength if the twisting moment of both the shafts is the same.Twisting moment determines the ability of a shaft to resist the applied torque without failure. It is given by the formula:
T = τ × Zp
Where:
T = Twisting moment
τ = Shear stress
Zp = Polar section modulus
Equal twisting moments imply that the shafts will experience the same level of stress and deformation under the applied torque, ensuring they have equal strength.
Therefore, Option D is the correct answer.
