Friction

Three tests are done through a Gizmo to determine how radius, mass, and velocity affects centripetal acceleration of an object undergoing uniform motion. The results show centripetal acceleration is affected by radius and velocity but not mass. It gives a better understanding to why objects in uniform motion accelerate towards the centre of a circle. Introduction The purpose of this lab is to determine how the radius, mass and speed of an object can affect the centripetal acceleration of the…

Vertical dimension (VD) defined in the Glossary of Prosthodontic Terms as "The distance between two selected anatomic or marked points”. Occlusal vertical dimension (OVD) defined as "The distance between two selected anatomic points when in maximal inter-cuspal position”.(1) The OVD is determined by the repetitive contracted length of the elevator muscles which sets the jaw-to-jaw relationship.(2) During growth and development OVD affected by three factors: Growth of the ramus, gonial angle of…

Grant Alexander Pd#6 11 November 2016 Trebuchet Engineering A trebuchet is a machine used in medieval siege warfare for hurling large stones or other missiles. How this machine works is not to complex but is also fascinating. The object that is being shot is held in the sling, which is on a launch trough whose job is to make sure the shot is straight. Also the trough is there to prevent the sling getting caught in the framework of the trebuchet. When putting the arm of the trebuchet down,…

1. What is the GPS Standard tied to this project? The GPS Standard tied to this project is - S8P3. Students will investigate relationship between force, mass, and the motion of objects. 2. How does your rubber band car show Newton’s 1st Law of Motion? The first law states an object will stay at rest until acted upon unbalanced force. The car is at rest until the rubber band is twirl all on the stick. This mean a force has to be added for the rubber-band car to move. 3. How does your rubber…

Purpose The purpose of the lab is to design an experiment to verify the spring constant for an unknown spring, also known as k, how much a spring resists change (compression or expansion). We used a method changing a mass and measured the change in x.

Newton's Second Law: It describes what happens to the body when it is affected by force, as it shows the relationship between the force affecting the body, and the movement acquired by the body. Through the study of Newton's first law, we see that in the absence of an effective force on an object or the existence of a group of balanced forces affecting it, This body will be in a state of stillness or regular movement in the straight line. We continue to study the movement of objects when a force…

The similarities and differences of Kinetics of a Particle: Work and Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a…

Projectiles, such as the ones shot from cannons, are affected by drag or air resistance. The amount of drag exerted on to an object is affected by many different factors, such as air density and the size of the projectile. It is important to understand drag, as it affects the distance an object is able to travel if it is not influenced by outside forces, such as a cannons projectile. The equation for drag is shown below. F=pCA/2 v^2 p = The density of the air. C = The drag coefficient of the…

Drum servo relates to drum brakes but more specifically the leading and trailing edges of the shoes. Drum brakes can have effective self-servo characteristics based upon which way the shoes are hinged, this has the effect of increasing stopping power without any additional effort by the driver because the rotation of the drum. The shoes within the drum have a leading edge and a trailing edge and are designed so that the leading edge comes into contact with the drum before the trailing edge. The…

is a problem that engineers face. It is caused by friction in pipes which is also called the friction head loss and that happens because of viscosity and pipe wall friction. Energy loss also happens due to local losses which occur at valves and sharp bends. Local losses are also known as minor losses because their effect is normally small in long pipelines. To understand the relationship between Reynold’s number and friction factor, the pipe friction experiment has been done. This experiment was…
