- TASK A hydraulic cylinder with a bore radius of 100 mm and an outer radius of 200 mm has been designed to withstand a maximum internal pressure of 200 MPa in service. During operation, the pressure within the cylinder is retained by a freely sliding piston. The steel used in the manufacture has Young's modulus of 210 GNm-2 Note: There is no axial stress generated in the cylinder wall in this application. 1. Elastic Stress Distributions in a Single Cylinder a) At an operating pressure of 200 MPa, calculate using Lame's equations the radial and circumferential stresses at the cylinder bore and the outer surface. Graphically present (sketch) the general form of variation of each of these stresses across the cylinder wall, clearly indicating the calculated values at the cylinder bore and at the outer surface. b) For the same operating pressure, calculate the maximum shear stress values at the cylinder bore and the outer surface. Hint: For axisymmetric problems, there are no shear stresses…H.W no. 2 Q1) 28 N.m torque is needed to turn the bolt around its axis as shown in the Figure (1) below.

- 1. You are tasked to design a shaft for power transmission through a belt and pully at its right side. The shaft is supported by a thrust bearing at A and a journal bearing at B. a) Determine the support forces the bearings have to "bear". (In machine design, this step is necessary for selecting the correct bearings from the catalog) Tip: Journal bearing can only support lateral (radial) force, like By in this problem, while Thrust bearings can support axial and lateral forces, like A, and A, in this case. b) Upon inspection of the shaft, you decide that the cross-section C needs to be evaluated to avoid mechanical failure. Find the resultant internal loadings acting on the cross-section at C. If the shaft diameter at this section is 0.3 mm, what are the average normal and shear stresses at this section? 700 N/m IIII C |--1m+1 m +1 m+15m 2m D 1 kN1) The rotating solid steel shaft (Fig.1 a) is simply supported by bearings at points B and C and is driven by a gear (not shown) which meshes with the spur gear at D, which has a 150 mm pitch diameter. The force F from the drive gear acts at a pressure angle of 20°. The shaft transmits a torque to point “A" of TA = 300 N.m. There is a step at point "C" as shown in Fig.1 (b), assume that D/d ratio is 1,09 and fillet radius (r) is 2,5 mm. a) Find the stress concentrations at point "C" due to bending and shear loads (Initially assume d=50mm). If the shaft is machined from quenched and drawn steel with Sy= 420 MPa and Sut=560 MPa and b) using a factor of safety of 2.5, determine the minimum allowable diameter of the shaft at "C" based on a static yield analysis using the distortion energy (DE) theory. If the shaft with a diameter (d) of 32 mm is made of a brittle material with Suc = 420 MPa and c) Sut=360 MPa, determine the factor of safety of the shaft at "C" based on a static analysis…Please answer in this format.
