Question 4 A 1.5-inch diameter shaft yields is applied with a torsional load T shown in Figure Q4. The shaft is made of a material with a yield strength of 180 MPa, an ultimate tensile strength of 250 MPa and an ultimate shear strength of 230 MPa. SINGAPORE UNIVERSITY OF SOCIAL SCIENCES (SUSS) EAS303 (a) (b) Figure Q4 T Page 4 of 7 Tutor-Marked Assignment Solve for the maximum allowable torsional load that can be applied on the shaft before it experiences material yielding. (6 marks) Apart from meeting the strength requirement, appraise TWO (2) other desirable material properties for the shaft.
