PROBLEM (5) The wall of an air compressor's cylinder liner is 5 mm thick. When cold,...
A thick-walled steel cylinder with internal diameter = 16 mm and external diameter = 24 mm is subjected to a gradually increasing internal pressure P. I. Using accurate formulation, determine the value of P and sketch the distribution of radial, tangential and maximum shear stresses when: a. The material of the cylinder first commences to yield. b. Yielding progressed to mid-depth of the cylinder wall (at D= 20 mm ). c. The material of the cylinder suffers complete collapse (fully...
with steps please Question4 A thick-walled cylinder of mild steel with internal diameter of 80 mm and external diameter of 120 mm is loaded by internal pressure. The yield strength of the material is 300 MPa. a. Find the internal pressure required to initiate yielding in the cylinder using Lame's formulation. Sketch the stress distribution giving significant stress values. b. Find the plastic limit pressure at which the cylinder is fully plastic using non-linear formulation. Sketch the stress distribution giving...
Q2 A 200 mm diameter cast iron pipe with wall thickness of 15 mm is carrying water when the outlet is suddenly closed. Calculate the maximmum discharge if the pressure rise is not to exceed 180 kN/m2 (a) assuming the pipe is rigid; (b) allowing for hoop stress but not longitudinal stress in the pipe wall; (c) assuming the pipe to have expansion joints throughout its length. (K-2.1 × 109 N/m 2, E 100x 109 N/m2) Q2 A 200 mm...
An AISI 1030 cold-drawn steel tube has an OD = 45 mm and wall thickness 5 mm, and the pipe is subjected to internal pressure only. What maximum internal pressure can this tube withstand if the largest principal normal stress is not to exceed 95 percent of the minimum yield strength of the material? Draw a 3D Mohr’s circle for the tube
Question 2 The pressure gage in an air cylinder reads 1,680 kPa. The cylinder is constructed of a 12-mm thick rolled-steel plate with an internal diameter of 700 mm. The tangential (hoop) stress (MPa) inside the tank is most nearly: O a) 25 MPa ob) 50 MPa O c) 77 MPa od) 100 MPa In the plate shown, it is required that the stress concentration of a hole does not exceed that at the fillet. The hole diameter is: mm...
MEE2001/2015 Q5. A thin walled steel cylinder with 10 mm wall thickness and internal diameter of 200 mm (Fig. Q5) is subjected to an internal pressure, p. The steel used for the cylinder has a yield stress of 240 MPa. +F 200 mm Fig. Q5 (a) If a tensile axial force of 1MN is applied to the end plate, show that the maximum internal pressure that can be applied before the cylinder yields according to the Tresca criterion is 16.2...
5. A holding fixture for a work piece 1.5 inch thick at clamp location is being designed. The detail of one of the clamps is shown in the figure. The spring is required to drive the clamp upward while removing or inserting a work piece. A clamping force of 10 lbf is satisfactory. The base plate is 5/8 inch thick. The clamp screw has a 7/16 in-20 UNF thread. Allow 0.05 inch diametral clearance between screw and the inner coil...
summatize the following info and break them into differeng key points. write them in yojr own words apartus 6.1 Introduction—The design of a successful hot box appa- ratus is influenced by many factors. Before beginning the design of an apparatus meeting this standard, the designer shall review the discussion on the limitations and accuracy, Section 13, discussions of the energy flows in a hot box, Annex A2, the metering box wall loss flow, Annex A3, and flanking loss, Annex...
summarizr the followung info and write them in your own words and break them into different key points. 6.5 Metering Chamber: 6.5.1 The minimum size of the metering box is governed by the metering area required to obtain a representative test area for the specimen (see 7.2) and for maintenance of reasonable test accuracy. For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
