Task force

In the system, focusing on the block, there are two forces residing on the block, which are its weight and its normal force that keeps the block from freefalling. However, normal force is perpendicular to the direction of the block’s displacement resulting on work done by the normal force because cos (90) is zero. Therefore, finding the total energy of the system, there is only initial potential energy due to the block’s…

able to exert a normal force on the balloon which equals the force due to gravity. This allows the balloon to be held up until there is a new force applied to it horizontally. The train begins to move forward and creates more tension on the string which is tied to both the balloon and the train. Once the train begins to move, more forces are applied to the balloon. These forces include both tension and friction. Since there is no structure opposing the gravitational force once it is pulled to…

Rockbolts as a ground control technology are just one in the very long list of ground control technologies that exist in mining and civil applications. The simplicity and reasonable cost associated with rockbolts are the primary driving forces for the research causing their wide variations for numerous public and private uses. The ease of calculation and implementation also makes rockbolts a go to option for engineers who would rather spend more time calculating other variables during a job…

Afghanistan: There were many challenges in the military but I am choosing to write about one scenario that made me realize what type of person I am. Even though I had struggle all through school, I was surprisingly good at being a Marine. Once I finished my first year in the military my parents grew to be pretty comfortable with the idea of me being in the corps. I think it is because they saw that I was finally growing up. In the Marine Corps they do not care about excuses and they definitely…

Galileo Galilei was born in Pisa, Italy in 1564 during the Renaissance.This was a rebirthing period in Europe started off in Italy for art, philosophy, and sciences. The Renaissance brought back many ideas from Ancient Greece and Rome introducing many scientists like Galileo. Attending the University of Pisa originally going to study medicine, he was taught the Aristotelian view on the world, later questioning it making way for many of his greatest discoveries. He was an outstanding astronomer,…

Intent supports mission command and guides joint forces by an understanding of how their higher commander visualizes the operation and what the desired end state looks like. Subordinates are delegated the authority to make decisions “wherever possible”, which allows them to exercise initiative based on…

Have you ever thought about making a contraption that protects eggs when dropped from ten feet? This machine can consist of popsicles, a maximum of ten balloons, a raw and hard boiled egg, as well as dixie cups, a small plastic bag, and glue. As a machine can protect an egg breaking on the ground, so can machines protect rovers when landed on a planet. Through viewing this, you can find out what type of machine my partner and I will use for our very own egg drop, and where you would see it…

In Heart Of Darkness, Joseph Conrad discusses how the Europeans treat the native congo people. Throughout the novella imperialism is presented by the Europeans attempting to colonize the Congo region. Joseph Conrad explains the harsh exploitation of the Congo through the perspective of Marlow. Marlow sees how the natives are treated with disrespect as their rightful land is taken from them. By analyzing Heart of Darkness by Joseph Conrad through a new criticism lens, one can see that the…

very light, it is moving at an incredibly high speed relative to the duck. All moving massive objects possess this property of momentum, a quantity proportional to the mass of the object times its velocity. Momentum is what allows objects to exert forces; it is the mechanism whereby two objects in a collision can influence one another. When two objects collide, they both enter the collision with some momentum – both have some mass and some velocity – both leave with some momentum; however, the…

Do you want to know what makes super cars go fast? Tune in to this science project to find out. In this science project, you will see aerodynamics, drag, and wind speed do its process on cars. In my experiment,on each car, there are streamers on them.When my wind tunnel turns on, streamers that fly everywhere will represent drag, and streamers that stick to the car will represent aerodynamics. In real life, they use smoke to figure out where drag is.Sometimes, they will put streamers on the car…
