machine using G-codes‚ M-codes in a CNC program. * Equipment: Minitech CNC machine (Series 2) * Machine introduction Most CNC milling machines are computer controlled vertical mills with the ability to move the spindle vertically along the Z-axis. This extra degree of freedom permits their use in die sinking‚ engraving applications‚ and 2.5D surfaces such as relief sculptures. When combined with the use of conical tools or a ball nose cutter‚ it also significantly improves milling precision

E204: TORQUE: SECOND CONDITION OF EQUILIBRIUM IBAÑEZ‚ Jonen Lery L. OBJECTIVE A torque is an influence‚ which tends to change the rotational motion of an object. One way to quantify a torque is force applied times the lever arm. In this experiment we consider the systems in equilibrium and its applications and how the forces acting on the system affect torque. To serve as a guide there are objectives set in performing this experiment. First objective is by the second condition applied to the

his/her back leg by leaning over with the upper body just enough distance. Since the leg has less mass‚ it must be stretched farter away from the center of gravity as the heavier torso bends forward a smaller distance so the force vectors across the x-axis are equal. If properly executed‚ the gravity’s downward push (due to the force of gravity) and the floor’s upward push (due to normal force) will be aligned straight through the dancer’s body to the point of contact with the floor. This will equate

both efficient and non-efficient portfolios. While calculating the returns‚ the expected return of the portfolio for CML is shown along the Y- axis. On the contrary‚ for SML‚ the return of the securities is shown along the Y-axis. The standard deviation of the portfolio is shown along the X-axis for CML‚ whereas‚ the Beta of security is shown along the X-axis for SML. Where the market portfolio and risk free assets are determined by the CML‚ all security factors are determined by the SML. Unlike

Windmills often have 3 blades that connect to a shaft. Once the blades detect the wind and begin rotating‚ they harness the power of the wind. There are two different types of windmills‚ horizontal axis and vertical axis. Vertical axis windmills were often used in the early years‚ while horizontal axis windmills are what we see today. They use angled propeller blades that create friction when if faces the wind‚ which enables it to rotate. Many windmills are used for pumping water. Wind pumps are

Guns‚ Germs‚ and Steel Book Review The book Guns‚ Germs‚ and Steel features the work of the author Jared Diamond. In his book‚ he mentions his answer to how different human societies became so diverse. Diamond doesn’t use racist answers‚ he gives an answer based on the geographical location of these diverse societies. He explains many concepts on how the location of a society can make them more diverse and more powerful than other societies. He shares many examples in history to support his thesis
