The radius of mohr's circle of stress of a strained element is 20 N/mm2 and minor principle tensile stress is 10 N/mm2 the major principle stress is

If a circular shaft is subjected to a torque T and a bending moment M, the ratio of maximum shear stress to maximum bending stress given by:

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): The cross-sections of the shaft which are plane before twist, remain plane during and after twist.
Reasons (R): The twisting moment does not vary with the radius of the shaft.
In the light of the above statements, choose the most appropriate answer from the options given below:

Sensor used to measure the speed of rotating shaft is called:

A solid circular shaft of diameter 'd' is subjected to a combined bending moment 'M' and torque "T. The material property to be used for designing the shaft using the relation \(\frac{16}{\pi d^3} \times \sqrt{M^2+T^2}\) is:

A solid circular shaft is required to transmit a torque of 100 Nm. If the permissible shear stress for the material is 180 MPa, the diameter of a shaft in mm is:
