Question: shear modulus 65 gpa anserws a 37427 mm b 449...

Question details

D .R he pafalliel shartsvSten showil suppofts a toroue o 3.5 kN-m applied E which is then transmitted to shaft ABC through the speed reduction gears B and D with radii of 101 mm and 39 mm, respectively. If the allowable shear stress for these solid shafts is 340 MPa, determine the minimum diameters (mm) for (a) shaft DE and (b) shaft ABC. Also using the minimunm shaft diameters, detemine (c) the shaft deflection 2L 3L (deg) at B with respect to A and (d) the total angular deflection (deg) of end E with respect to A. Assume the unit length L 0.4 m and the shear modulus of 65

Shear Modulus: 65 GPa

Anserws: A. 37.427 mm B. 44.9 mm C. 5.34 D. 38.387
