Assertion A solid shaft is found to be stronger, than a hollow shaft of same material. Reason The torque required to produce a given twist in solid cylinder is smaller than that required to twist a hollow cylinder of the same size and material.

Question

Assertion A solid shaft is found to be stronger, than a hollow shaft of same material. Reason The torque required to produce a given twist in solid cylinder is smaller than that required to twist a hollow cylinder of the same size and material. (A) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion (B) If both Assertion and Reason are true but Reason is not correct explanation of the Assertion (C) If Assertion is true but Reason is false (D) If Assertion is false but the Reason is true

A hollow shaft is found to be stronger than solid shaft of the given size and material. Hence, Assertion is false. Torque required to produce a given twist in hollow cylinder is greater than that required to twist a solid cylinder. Hence, Reason is true.

Q. Assertion A solid shaft is found to be stronger, than a hollow shaft of same material. Reason The torque required to produce a given twist in solid cylinder is smaller than that required to twist a hollow cylinder of the same size and material.

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion

If both Assertion and Reason are true but Reason is not correct explanation of the Assertion

If Assertion is true but Reason is false

If Assertion is false but the Reason is true

A hollow shaft is found to be stronger than solid shaft of the given size and material. Hence, Assertion is false. Torque required to produce a given twist in hollow cylinder is greater than that required to twist a solid cylinder. Hence, Reason is true.

Q. Assertion A solid shaft is found to be stronger, than a hollow shaft of same material.
Reason The torque required to produce a given twist in solid cylinder is smaller than that required to twist a hollow cylinder of the same size and material.
