    1- Summary This study is based on the analysis of pressure distribution around a NACA 23015 airfoil section with a flap of length equal to the 30% of the cord at different angles of incidence and flap settings. The experiment was performed in a non –return wind tunnel at a Reynolds number of 4.4×〖10〗^5 and at a Mach number of 0.073. It is of note that increasing incidence will increase lift produced until the critical angle of attack, where the airfoil stalls; moreover, deploying a flap will increase the maximum lift produced, but will produce drag and cause an early stall. 2-Introduction The aim of this experiment is to investigate how the pressure difference about the upper and lower surface of an airfoil can affect its aerodynamic performances…

    “Geometries in Cold Welded Steel.” This artwork was presented by the artist Tom Duchscher. Duchscher has been teaching design, sculpture, and ceramics at MJC for the past 40 years. His work has been exhibited throughout northern California and pacific northwest. For the past four decades Duchscher has dealt with the exploration of geometric forms and has focused on the element of line. This has allowed him to create illusionary and actual phenomenon. The use of linear parallel in his artwork has…

    This can be seen when the different races speak straight into the camera about they hate other races. It can also be seen when Lee himself looks into the camera and says, “You’re all racists”. Lee also uses different lighting to expose the extreme heat that the characters are faced with. Overall, Lee produced his film by exploiting pre and post classical Hollywood cinema techniques by using music and facing the camera on the characters in different angles and using close up shots. Having…

    because reflective markers were added on the bony landmarks of their hip (greater trochanter) knee (lateral epicondyle) ankle (lateral malleolus) and toe (5th metatarsal). Trials runs were given to the participants before the testing, to familiarize with the experiment. Additional time measures were noted of every trial and divided it by the distance (4.5 m) in order to calculate the speed in meters per second (m/s). Experimental Protocols: For the Motion analysis system, the QualisysOgus 3+…

    isosceles triangle the base angles are congruent , so that means that angle Q is equal to angle P, since angle Q is 45 degrees, angle P is also 45, and because a triangle has 180 degrees, the remaining angle(O1) must be 90 degrees. This proves that the triangle PO1Q, is a right triangle, and…

    In this lab we will explain how to deduce the equation landing position of the ball thrown by the robotic arm stand. We must create the equations in terms of the radius, height, arm rotation speed, and release angle. The equations must be made with those variables because, those variables are what can change where the ball will land in the cup, and will make the equation more useful to the client. To make sure the equation will remain accurate we have to keep track of all the units throughout…
