The aim of the Stress Concentration Experiment was to observe the stress concentration factor/feature for a set of mild steel specimens with various irregularities in each sample. These irregularities or “stress-raisers” include any notches and holes which vary in size (radius) and placement on the specimen (edge notches or holes) that may have an effect on the flow of stress. With the use of a Hounsfield 50 kN electrically operated tensile testing machine and 12 1-mm thick mild steel test…

SCIENTIFIC REPORT PROFORMA YEAR 8 Task 1 2018 Student name: Jacob Teacher: Miss Bianchi Class: 8.5 Due: Tuesday 27th March 2018 TITLE: Bouncing Balls BACKGROUND RESEARCH: Physics: is the main part of science involved with the character and properties of matter and energy. Matter of physics includes: mechanics, heat, light-weight and alternative radiation, sound, electricity, magnetism, and also the structure of atoms. Physics has many things that help us or things we use and we…

3.1. Growth Kinetic of strain: The growth curve of strain in both of mediums is shown in Fig. 1 (Supplementary data). It was apparent that 2 hours after nucleation of culture, strain interred to logarithmic phase and continues for 10 h in MRS broth and 12 h in PPM medium. Sonication continued in logarithmic phase in 2 h intervals. 3.2. The effect of ultrasound on growth kinetic: The growth curves plotted for the two condition (with and without sonication) (Fig. 1), growth kinetic parameters…

COMPOSITION OF UNIVERSE As we know, the Universe comprises of space, time and everything perceived to exist physically including all forms of matter and energy and interaction going on between them. Space and time are two basic correlates of universe. In these correlates there is matter and energy scattered around. There is interaction going on between matters, energies and between matter and energy on account of endless processes. These processes are governed by universal laws as explained in…

Long Jump Procedures: The participant has to stand behind the line and has to jump off of both feet and attempt to jump as far as possible while landing on both feet. The participant gets three chances to jump as far as they can, then they record their data. Advantages: This test does not take very long to do and it does not require a lot of equipment. Disadvantages: It takes some form to know how to do this properly so some participants may have an advantage over others. Validity: it is a good…

the effect of the personalized mus- cle geometry on the force generation in the lower limb. DistMo defines the model personalized with the PA ob- tained with the straight line approach, while CenMo describes the model personalized with the PA obtained with the centroid line approach. GenMo represents the model that used the generic values of the PA from OpenSim (PARF = 13.9◦, PAV I = 4.5◦, PAV L = 18.4◦, PAV M = 29.6◦). The inter-model force and moment variations between GenMo, DistMo, and CenMo…

automobile carburetor is a common example of Bernoulli’s principle and the convergent-divergent process. The following is a description of a practical demonstration of how a gas turbine operates. A blown-up balloon does nothing until the trapped air is released. The air escaping rearward causes the balloon to move forward (Newton’s…

By Brigid Garrett , Wyatt Mullings, Jesus Sanchez, and Lydia Blaisdell Cable Sensation Russky Bridge, Vladivostok, Russia. What are Cable/Stayed Bridges? A cable/stayed bridge is a bridge that has two towers with cables supporting the bridge itself, as shown above. The towers are called pylon, the crossing area itself is called the roadway. The cables are obviously called cables. The supports underneath on the sides are called abutments, The foundations are located under the ground on the…

“Bicycle, bicycle, bicycle. I want to ride my bicycle, bicycle, bicycle. I want to ride my bicycle. I want to ride my bike.” High pitched in all its glory—at the top of our lungs—it was “Bicycle Race” by Queen, or The Bicycle Song in the terms of an unknowing five-year-old. It started my morning for three years. Katherina would rock out to and sing this memorable song, even through its fiftieth time, with a joy that few siblings can muster. Sometimes loud, sometimes in a fit of giggles, but…

Objective: The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces. Principles being examined: The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the…
