A thick wall pipe with an inner diameter of 120mm and an outer diameter of 180mm is subjected to internal pressure P. The material properties are given as E = 200 GPa, G = 77 GPa, v = 0.3 and o, = oult = 250 MPa. If the required safety factor is 1.6, find the following: i. The maximum inner pressure according to the Maximum Normal Stress criterion. ii. The maximum inner pressure according to the Maximum Distortion Energy criterion. iii. Sketch the stress distribution across the pipe wall thickness. iv. Name one change that can be done to increase the allowable inner pressure.

A FEM analysis was used to analyse the safety of a mechanical component made by an average steel (E = 2 × 105 MPa, v = 0.25, o, = 600 MPa). For a given loading scenario, the stress tensor E in a critical point is: Try -81 -186 Try Oyy 186 -37 -319 Calculate the von Mises equivalent stress oyM and indicate whether or not the stress condition is safe with respect to the related failure criterion. OVM = MPa Is the stress condition safe with respect to the related failure criterion: Oa. Yes Ob. No
3) A thin-walled cylindrical pressure vessel of diameter of 1.5 m is subjected to an internal pressure that varies continuously from p_min= 0.8MPa to p_max = 4 MPa. Determine the pressure vessel thickness, t, if the pressure vessel is made from steel with an ultimate strength S_u=400 MPa, a yield strength S_y=300MPa, and an endurance limit S_n-150MPa and a safety factor of two is desired. Use Modified Goodman and the maximum normal stress theory.
A rigid DC switch is attached to the 20 mm radius solid aluminum AB shaft. The forces of P= 3kN in the + y axis direction and F = 4kN in the -z direction were applied to the DC element from the C end. Check the safety of the pipe according to the tresca and Von-mises criteria. Taltow = 80MPA, Gallow = 160MPA. Safety factor 2. r 20mm A 1m P 100 mm 2.
Why does the answer of this problem consider radial stress if it is a thin walled?
Quickly please.
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
The drive from a motor to a machine is by means of a crossed flat belt. The shat of the motor and the machine are parallel and 1.2 meter apart. The motor pulley A turns at 1440rpm and has a diameter of 250mm. The machine B rotates at 450rpm. The belt is made of lether. The safe tensile stress is 7MPA and the density is 900kg/m. The dimensions of the belt are 50mm x 6mm. µ = 0.2. Dermine: The length of the belt required The maximum power that can be transmitted The maximum torque on the driving pulley The maximum torque on the driven pulley
