AB aluminum rod (G= 27 GPa) is glued to BD brass rod (G = 39 GPa) as shown in the figure. The CD part of the brass rod is hollow and has an inner diameter of 40 mm. TA 600 Nm, TB 1200 Nm according to the loading state given below a) Draw the torsion moment diagram. b) Calculate the angle of rotation of tip A with respect to D. ΤΑ 36 mm A TB 400 mm B 60 mm C 375 mm D 250 mm

I tried this problem the only way I can think of and I don't know what I could be missing it would be really helpfull if you could show me what I am misssing in my calculations

A steel torsion bar AB with diameter d = 34 mm, and ductile material of tensile yield strength Sy = 276 MPa is attached to a rigid arm at A, supported by a bearing at C, and fixed at B, as the picture shows. At the right end of the arm is mounted the wheel on which the vertical force P acts from the ground and which passes through the center of the wheel. If bearing C acts as a simple support and the effect of transverse shear due to P is negligible, determine the maximum force P (in kN) that can be applied to the wheel. Consider a factor of safety n = 2.5. Use the maximum energy of distortion failure criterion and do the analysis on bar AB (torsion bar) in the section where the bearing is.

The rod shown below is of diamater 70 mm and is fixed at one end. It is subjected to 500 N.m and 300 N.m torsional moments as shown. Sketch the distribution of the internal torsional moment along the length of the rod. Also find the torsional shear stress at points A and B, and also the largest shear stress in the rod. Point B is to the left of the 500 N.m torsional moment and A is on the right of it. Round-up your answers to the nearest 1/100th of an MPa. y 35 mm 20 mm 500 N.m 35 mm- 300 N.m Torsional shear stress at A = MPа %3D Torsional shear stress at B = MPа Maximum shear stress = MPa %3D
