A connecting rod is a machine member which is subjected to alternating direct compressive and tensile forces. Since the compressive forces are much higher than the tensile force, therefore the cross-section of the connecting rod is designed as a strut and the Rankine formula is used. A connecting rod subjected to an axial load F may buckle with x-axis as neutral axis in the plane of motion of the connecting rod, {or} y-axis is a neutral axis. The connecting rod is considered like both ends hinged for buckling about x axis and both ends fixed for buckling about y-axis. A connecting rod should be equally strong in buckling about either axis [8]. Let, A = cross sectional area of the connecting rod. l = length of the connecting rod. c = compressive …show more content…
8 Total Deformation of Cast Iron Connecting Rod Total deformation of connecting rod after applied pressure of 16 Mpa is shown in figure no. 8.Small end of connecting rod will show the maximum deformation & there will be no any deformation at big end of connecting rod as it is fixed. The maximum deformation of 1.252 e-8 mm will occur at small end. Fig. 9 Von- Mises Stress of ASTM A216 Gr WCB Connecting Rod For the other material ASTM A216 Gr WCB same pressure of 16 Mpa is applied and the stress developed is approximately as similar to the connecting rod made with material of cast iron. Figure no. 9 indicates the maximum and minimum stress developed in connecting rod at small & big end. The equivalent stress maximum and minimum values are 71.347 MPa and 4.4955e-5 MPa respectively. Fig. 10 Elastic Strain of ASTM A216 Gr WCB Connecting Rod Elastic strain region at small and big end of connecting rod is shown in figure no. 10. The maximum and minimum equivalent strain values are 0.00033975 and 2.1407e-10 respectively. Due to applied pressure there will be change in original dimensions of the connecting rod and hence strain developed can be

A schematic of the SHPB facility used in the present work is presented in Figure 2.1. The Split Hopkinson Pressure Bar consists of an incident bar, transmission bar and a projectile termed as the striker bar all made of maraging steel which holds a nominal yield strength of 2500
Rigid body motion does not change the length of a vector joining the pair of points inside the body and has no concern with the strain analysis. When external forces are applied on an elastic body, the body undergoes deformation. Due to the elasticity of the body, there comes into play a force which resists the deformation. This force is called stress force. Clearly, the deformation of the body is accompanied by the stress force. In other words, stress and strain occur together in inelastic body. There are two types of elastic deformation: (i) Dilatation and (ii) Shear strain set up in the body in such a way that there is a change only in volume but no change in shape, is called dilatation. In the shear deformation, there is a change in the shape of the body without a change in its volume. Dilatations are further categorized into two kinds: compression, in which volume is reduced; and rarefaction, in which the volume is
Throughout history, there have typically been shifts from harmony to conflict between the three branches of American government. The framers of the Constitution created the executive, legislative, and judicial branches of government in order to form a system of checks and balances to prevent a single area of the government from becoming too powerful. This system of checks and balances has been accompanied by vast amounts of discord throughout its existence. The shifts in interbranch relations can be seen through Congressional deference prior to and during the beginning of the Vietnam War, Congressional resurgence after the Vietnam War, and a shift back to Congressional deference following the attacks of 9/11.
John Walker, from the book Modern Metalworking states that before welding to check the welder to make sure the leads and the grounds are connected properly because the temperature of the weld is determined by amps (2). There are different sizes of rods, these include eighteen gauge, sixteen gauge, ten gauge, one-eighth gauge, three-sixteenth gauge, and one-fourth gauge (Walker 30-4). When welding be sure to have the correct welding speed. Weld speed is indicated by the looks of the puddle and the ridge of the bead (Walker 30-14). Rob Timing from FabricationandWelding.com states that the filler metal fills the cavity made when
How long would it take before you give up on something you desire, a day, a month, a year? In Jerry Spinelli’s book, Knots in My Yo-Yo String, it took him about thirteen years and four novels before Spinelli succeeded in getting his first book published. Success in writing, like success in anything, is not likely to happen on the first try it comes through hardship. In this story, his career starts from a football game, to rejection and to publishing his first book.
I as well as many people don’t understand the symbolism of the the hangman’s knot or the history behind its uses. I have always came to understand that it was an offensive knot to others because of the lynchings going on during slavery time period. Even today the hangman’s knot still plays a role in modern hate crime acts; However the hangman’s knot dates back to as early as the 16th century. The brutality portrayed by the knot brings out many feelings among many different people, And with that causes many acts of violence and rage toward others. The hangman’s knot, or also known as noose is a hard subject for many African Americans to talk about or discuss. Because at the time of these crimes the African American race was looked down upon. They were treated like animals and were never given the least bit of respect, they were tortured, beaten, and then hanged. I can agree that if this happened to my ancestors I would be offended by the many things that used to happen, and the symbols that are used in hate crimes today.
The failure mode in Case 2 is similar to that in Case 1, but the buckling load was increased in Case 2 to reach 51% of the total applied loads rather than 44% in the previous case. The end braces at the top of girder helped to resist and minimize the lateral moment of the webs, Figs 18-19. As a result, the load buckling increased (capacity) and the bending and buckling displacement decreased (0.021", 0.1"), as shown in Figs 16-17.
Laws such as the lever law and Euler’s Buckling Theorem come into play when testing and competition begins. A structure of wood and glue surely has much more to offer than meets the eye.

L = Length of the conductor(m). A = Area of cross section of the conductor (m2). = the resistivity of the material of which the conductor is made. (Îm) The experimental determination of the resistivity of a material. involves measuring the resistance of a specimen of the material.
Moment loads are divided into two categories such as bending moment and torsion moment. The stresses due to the moments can be illustrated as in the following figure 3.11;
A static structural analysis determines the displacements, stresses, strains, and forces in structures or components caused by loads that do not induce significant inertia and damping effects. Steady loading and response conditions are assumed; that is, the loads and structure’s response are assumed to vary slowly with respect to time. A static structural load can be performed using the ANSYS.
