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…

Stress: Stress is defined as ‘’the force across a boundary per unit area, for all orientations of that boundary.’’ It is derived from force, a physical quantity and area, a geometrical quantity. Therefore, stress is also characterized as a fundamental quantity, like velocity, energy, etc. that can be brought under quantification and can be analyzed without any obvious attention of the physical grounds of the material or of its nature. Example: When a solid bar is supporting a load, each…

its potential energy? When the pendulum of a clock swings back and forth, the pendulum reaches its maximum potential energy at the top of the swing, and it reaches its maximum kinetic energy at the bottom of the swing. In the absence of frictional forces, the pendulum’s kinetic energy will be equal to its potential energy at the bottom of the swing. 2. What is the difference between energy conservation and the principle of the conservation of energy? Give some examples of each. The difference…

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…

Static stability assessment with existing IMO A 469 criteria The primary objective of this section is to assess the static stability of the AHV during AHOs. Intact vessel capsizing prevention is a fundamental principle of fulfilling the ship stability requirement. The stability of a vessel is universally presented with a static stability curve, which describes the overturning moment required to incline a vessel to various angles for a given loading condition. This curve in principle similar to…

time now to teach them all a lesson that they never for get. Her play was to call Master Shaak Ti, Master Aayla Secura, Master Lumanaria, Padawan Barries Offrie now to her quarters now and then let them in. After that she would lock the door with force powers she could use and seal it for good then. She…

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…

In general, the experiment succeeded in demonstrating free-fall by dropping a tennis ball. Distance and time were documented to calculate velocity and acceleration, the quantities involved in linear kinematics. Graph 1 (distance vs. time) suggests a commonsensical relation - longer distance yields longer time. The only exception is at 1.0 m, where its time value (0.42 s) is less than that of a shorter distance (0.5s for 0.5 m distance). Average time was used to construct the graph, and there…
