+++ ++++ Figure 1: Thick walled cylinder subject to internal and external pressures

Tutorial Sheet Part 1 (Basics) A thin-walled pressure vessel has a diameter of 45mm, a wall thickness of 1.5mm and is subject to an internal pressure of 200 bar. For the outer surface of the pressure vessel calculate the: a. longitudinal stress b. circumferential stress c. radial stress 2. Calculate the same again but for the internal surface of the pressure vessel. 3. Calculate the factor of Safety of the vessel based on the pressure given a yield strength of 28 0MPA 4. Sketch the stress profile through the wall-thickness of the pressure vessel for the: a. longitudinal stress b. circumferential stress c. radial stress i6 the angwers wrong 2? amgwers Answers 01: Ja) 140 MРа N, b) 280MPа, с) 22: а) 140 MРа N, b) 280MPа, с) -20 МPа Q3: 1.0 [no factor of safety] О МРа

Answer the questions below for the following system. Young's modulus and Poison's ratio can be taken as 200 GPa and 0.3, respectively. a) Calculate and determine the stress state for point H using undergraduate level solid mechanics knowledge? b) Determine the principal stress values at point H using undergraduate level solid mechanics knowledge? Top view of section where H is located Point H no 300 mm 120 mm C .H 540 mm A Diameter of the pipe d=36 mm P=900 N

Part II. Longer problem focused on problem solving multiple steps. This problem will be graded based on process, clarity of work, and correct answer and units. a. A spring is stretched, with a force, F = 442 lbf, along the outside of a pipe as shown with a = 53° and ẞ 69° and the coordinates of the force are (15,37,-71 ). How far does the spring stretch if the spring constant is k=67 lb/in? Hint: The force that stretches the spring is the projected force along the pipe F (x, y, z)

Derive the formula of the critical radius for spherical wall.

Bar one has a Young's modulus that is bigger than that of bar two. This indicates bar one:

The tangential stress is produced twice that of the longitudinal stress in thin walled pressure vessel, which type of the stress is the most critical?

Correct answer is written below. Detailed and complete solution only. I will upvote, thank you.

Question 5. A component consists of two horizontal concentric solid cylinders, A and B, fixed together as shown in the diagram below. X mm x Cylinder A 800 mm x = OG Cylinder B mm 500 mm Cylinder A has a diameter of X=50 mm, a length of 800 mm and is made of steel having a density of 7800 kg/m³. Ymm Cylinder B has a diameter of Y=66 mm, a length of 500 mm and is made of aluminium having a density of 2600 kg/m³. The dimension is the distance from the left-hand end of the component to its centre of gravity at point G. Calculate and enter your answer, in mm, correct to three significant figures in the box below.
