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…

Two factors are required for proper operation of a gas turbine. One is expressed by Newton’s third law. The other is the convergent-divergent process. Convergent means approaching nearer together, as the inner walls of a tube that is constricted. Divergent means moving away from each other, as the inner walls of a tube that flares outward. Bernoulli’s principle is used in this process. The venturi of the common automobile carburetor is a common example of Bernoulli’s principle and the…

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…

 Make yourself in Shava Asana. Now raise whole body towards sky in such a way that that only shoulder and head is on the ground .  While inverting yourself balance your raised body with the help of your hands holding the back with bent elbows on the the floor ,making broad base for supporting upright straight body.  Try to keep raised part of body straight as shown in picture.  During this maintain normal breathing and stay in the posture for a while.  Now slowly slowly bring down raised…

parachute, which can be proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down. Another equation is a=v/t (acceleration=velocity/time) and a=(√2s)/t (acceleration=(sqrt2*distance)/time). The research question that this investigation will explore is: How is the drop time of a parachute affected by its mass? Photo 1: Parachute…

Motor & Gearbox The mirrors are required to rotate specific angles. To be able to achieve specific angles we need a stepper motor. The stepper motor is known to divide one revolution into equal steps which is our main requirements for the rotation of the mirrors. Figure ‎2-13: The Stepper Motor The following table shows the stepper motor specifications: Table ‎2-1: Stepper Motor Specifications Current 4.2 A Angle 1.8° Torque 8.34 N.m The desired torque calculated to withstand the mirror…
