PE Coursework Strengths The sport I have chosen is football. One of my main strengths (components of fitness) in football is my speed. The definition of speed is the ability to move quickly across the ground or moving limbs rapidly to grab or throw. In football, you use your speed for e.g; When you’re attacking and you are dribbling past a defender, you can use bursts of speed to blow past him. This means I get closer to the goal and have a better chance of scoring for me and my team. Also,…

Rosseland Radiation Model The Rosseland Model (Diffusion approximation model) is applicable when the medium is optically thick i.e. the optical thickness is much greater than 1 where a is the absorption coefficient of the medium, σ is the scattering coefficient of the medium and L is the average path length. The radiative heat flux is approximated as [3], (2.13) where qr is the radiative heat flux, Γ is the radiative diffusivity and G is the incident radiation. In contrast to the P-1 model…

INTRODUCTION • Energy is a scalar quantity. • It was first hypothesized by Newton to express kinetic and potential energies. • We cannot observe energy directly, but we can measure it using indirect methods and analyze its value. • Energy may be in different forms, such as potential, kinetic, magnetic or electrical. Potential energy of a system is by virtue of its location with respect to gravitational field. If an object has a mass m, located at elevation h, and acceleration due to gravity is g…

While designing any aerodynamic body an unspoken assumption of bilateral or mirror symmetry is taken into consideration. Argument against this bilateral symmetry states that “once the velocity of sound is exceeded, the laws of aerodynamics change in such a way as to make it seem inadvisable to arrange the components of an airplane side by side or abreast in a supersonic stream unless there are compelling reasons for such an arrangement.“ 2.1.1 Wave Drag This type of drag is formed as a result…

IV. Mechanical analysis for the manipulator arm In this section, the static analysis, forward kinematics and inverse kinematics for the manipulator arm will be discussed. A. Static Analysis The static analysis is very significant in manipulator’s design to roughly approximate the required torques from each motor. In our design, it is important to check the stability of the quadcopter that the manipulator is integrated on it in terms of manipulator arm center of mass shifting as function of…

Meshing of knuckle joint Figure 8.1 meshing of knuckle joint 8.2 Constraints applied on knuckle joint for analysis Figure 8.2 constraints applied on knuckle joint CONCLUSION After studying knuckle joint used in tractor-trailer then after making design and analysis of knuckle joint for stresses and deflection the following conclusions can be drawn: From the above results and discussion, Knuckle joint was design for 52860 N axial load by theoretical calculation. From theoretical…

Lab 6: Energy The intent of this lab is to show the relationships of energy to a system. For this experiment, we had a spring attached to a car, which was attached to a string that went through a rotary sensor and had a weight attached at the end. By stretching the spring, and causing the weight to drop nearer to the ground and bounce up we were able to determine: the angle of the string and rotations; the car position; height of the weight bouncing up and down; velocity; the stretch of the…

A skid steer loader is a versatile machine, and a must have for anyone in landscaping, large-scale construction, farming, or logging. It has a rigid frame and lift arms you can attach various tools and skid steer loader attachments to. Loaders may be track-equipped or four-wheel drive. The drive system of the loader has no transmission. Instead, it uses pumps and hydraulic motors to power the wheels or tracks. Wheels can drive independently of each other, which makes them very maneuverable.…

Difference between a racing dirt bike and a Trail dirt bikes Did you know that Racing dirt bikes is way different than riding regular dirt bikes? Most people think that they are the same, but they are not very similar. Racing is different from regular riding because of the bikes engin, their suspension, and their tires. Motocross bikes focus on different speeds. Trail bikes are meant for going threw mud and meant for more power. gearing up helps if your trails consist more of long…

To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the…
