A tubular shaft made of an aluminium alloy has a diameter of 80 mm and a wall thickness of 8 mm. If its shear yield strength is 200 MPa, calculate the maximum torque that it can sustain without showing any plastic deformation.

A 1 m length of 50 mm diameter steel bar is subjected to a torque  of 230 Nm.  Calculate the maximum shear stress exerted on the bar.  Assume a Young’s modulus  of 210 GPa and a Poisson's ratio of  0.3.

Compute the torsional shear stress in a circular shaft with diameter of 50mm that is subjected to a torque of 800Nm.

A thin-walled tube having a semi circular shape has an outside diameter of 50 mm and a wall thickness of 2mm. If the stress concentration at the corners is neglected,What torque will cause a shearing stress of 40 MPa in N-m?

A shaft with a diameter of 50 mm and a length of 1300 mm with a safe shear yield strength of 20 N / mm2 is subjected to 565 Nm of torque. What is the torsion angle and applicability? (G = 80GPa)

A drill rod with a diameter of 12 mm is made of high-strength steel alloy with a shear modulus of 80 GPa. The rod is to be subjected to a torque T. What is the minimum required length L of the rod so that the cross section at one end can be rotated 90⁰ with respect to the other end without exceeding an allowable shear stress of 300 MPa?

The internal diameter of a hollow shaft is 2/3 rd of its external diameter. Compare the strength and stiffness of the shaft with that of a solid shaft of the same material.

Bearing stress 4. Please provide proper discussion and illustration also complete solution and clear solution please thank you Determine the length of a square key to be used for a 3.73 kW, 1800 rpm electric motor if the motor shaft diameter is 35 mm and the width of the key is approximately one-fourth of the shaft diameter. The allowable shearing stress on the key is 2.45 MPa

What is the magnitude of shear stress generated in shaft of diameter 20 mm when 10 Nm torque is applied on it.

A steel shaft is to be manufactured either as a solid circular solid bar or as a circular tube. The shaft is required to transmit a torque of 1200N-m without exceeding an allowable shear stress of 40MPa or an allowable rate twist of 0.75deg/m. The shear modulus of steel is 78GPa. Compute the required diameter of the solid shaft & compute the required outer diameter of the hollow shaft if its thickness is 1/10 of its outer diameter.
