Various materials used for manufacturing a chain link are steel, stainless steel, carbon steel, alloys etc. The chain link which we have considered is used for hoisting purposes, this is because the oval shape is ideal for crane hook as the depth of the crane hook is greater than the width. We will study stresses induced in the link. It is necessary to study the stress distribution, deformation and deflection so as to avoid design failure and loss. The necessary information required for the project like material properties, type of load to be applied, intensity of load is taken from the textbook ‘Strength of Materials ’ by Dr. R. K. Bansal.
Study of deformable bodies will help researchers integrate the set parameters in a pontoon bridge to designing the pontoon bridge. Experiments can be done to acquire “strength” of materials. The objective of this stage is to specifically acquire strength, stiffness, and stability of a body. The experiment must be designed to help the researcher understand the reaction of a pontoon bridge’s strength, stiffness, and body stability to certain external loads and projective external loads. Projective external loads are assumed to be the maximum external forces that can occur in the pontoon bridge.
The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that affect wave speed - inertial properties and elastic properties. Elastic properties are those properties related to the tendency of a material to maintain its shape and not deform whenever a force or stress is applied to it. A material such as steel will experience a very small deformation of shape (and dimension) when a stress is applied to it. Steel is a rigid material with a high elasticity.
The interior diagonals are under tension under balanced loading and vertical elements under compression. If pure tension elements are used in the diagonals then crossing elements may be needed near the center to accept concentrated live loads as they traverse the span. It can be subdivided, creating Y- and K-shaped patterns. The Pratt truss is practical for use with spans up to 250 feet (76 m) and was a common configuration for railroad bridges as truss bridges moved from wood to metal. They are statically denominate bridges, which lend themselves well to long spans.
First, the device has to be able to accommodate different weights of the trainees. The materials for building it have to be strong enough not to be susceptible or crumble under the pressure of people exercising. Most of the machine is made up of durable metals such as aluminum or steel to avoid this issue. Accordingly, the invention provides an exercise apparatus for the performance of hamstring eccentrics and concentric. It comprises of a kneeling cushion which is leaning along its length; a foot secure is positioned at the upper end of the kneeling buffer, and a frame for supporting the kneeling protection is also in an inclined position with the foot anchor.
This helps to make it easily integrated into the construction process. The Disadvantages of Truss Bridges 1. Very Heavy Truss bridges are massive and weight quite a bit. In for the surrounding land to be able to support these bridges additional support is often needed. This may include making adjustments to existing structures around the bridge.
The load exerted on the beams will be caused by; the load from the self weight caused by the deck, loads resulted to by the live loads, weight exerted due to car skidding as well as effect of braking and horizontal loads as a result of temperature and movements such as wind. Due to this reason, the beam should be strong enough to carry the load. The design shape of the beam will be as shown below. There are a number of forces that will act on the beams and the bridge thus the beams should be constructed in a way they will be able to
This is the concept from the mechanics of material so the bone is also composed with this structure only to get high strength and to resist bending stresses. Remodeling and formation of the femur bone: Femur bone formation is a processes in the human body for the development of the critical structure. It is lifelong processes in this process we have two sub processes those are .Resorption .ossification Resorption is defined as the diminish of the previous bone (or) old bone. In the same order the ossification is defined as the formation of new structural femur bone. This process (formation) is important at the time of fractured bones because if this process is not enable then it leads to discontinues growth of the bone.
Furthermore, I have also found a pattern/trend in the graph, the graph has a steep slope only increasing due to the fact that the distance of the elastic band is also increased. The farther the distance of the elastic band, the larger the displacement of the tub will be. The reason behind this is that the longer the distance of the pull-back of the elastic band, the farther the tub will travel is because the farther the pull-back of
Futhermore, I was fascinated by the force method and displacement method for analysis of statically and kinetically indeterminate structures. The most fascinating and challenging course, however, is “Applied Elasticity - Finite Element Method” which provided me with theory of stress, theory of strain, and tress-strain
