Newton’s 2. nd. Law Lab- due . Thur. sday . by 11:59 pm. Friction . Lab Wednesday and Thursday. .. Friction Review. Lesson 9. Friction. Friction opposes a sliding motion.. A ramp is an inclined plane.. A ramp helps move objects.. You can use an inclined plane to help move an object to a higher or lower place.. What is the mechanical advantage of the ramp or incline plane?. 2. Newton’s . Second and Third. Laws of Motion. mass. acceleration/force. acceleration/mass. balanced forces. unbalanced forces. momentum. action. reaction. work. simple machines. lever. fulcrum. the tensions . T1 and T2 in the strings must satisfy which of the following relations?. (A) Tl = T2 (B) T1 > T2 (C) T1 < T2 (D) Tl + T2 = mg. Answer. As T2 is more vertical, it is supporting more of the weight of the ball. The . While a plan is flying, there are four forces. acting with and against each other. These forces. are:. . -lift. . -drag. . -thrust. -weight. Lift. Lift is the force that causes an airplane to rise. . FOR PLANE SOLIDS. FINITE ELEMENT ANALYSIS AND DESIGN. Nam-Ho Kim. Audio: Raphael T. Haftka. INTRODUCTION. Plane Solids. All engineering problems are 3-D. It is the engineer who approximates the problem using 1-D (beam or truss) or 2-D (plane stress or strain).. Inertial Reference Frames. Mass vs. Weight. Forces we studied:.  weight / gravity.  normal force.  tension.  friction (kinetic and static). Drawing Free Body Diagrams. Problem Solving . Things to Remember from Last Year. Forces applied at an angle. When forces are applied at angles other than 90. o. ,. we need to resolve the force into its component vectors. . Then, we . find the net force in each direction, . write our force equations (. CE 470: Steel Design. By: . Amit H. Varma. Design of Members for Combined Forces. Chapter H of the AISC Specification. This chapter addresses members subject to axial force and flexure about one or both axes.. https://. www.youtube.com/watch?v=0iYuF5dUalE. Purpose of an inclined plane is to lessen the force needed. Less force but larger distance. Inclined Plane. An object placed on a . tilted surface. will often slide down the surface. . Center for Astronomy Education (CAE) . http://astronomy101.jpl.nasa.gov. TPS for Problem Solving. Reformed Class. Two 50 minute lectures per week. Focused on introducing concepts using active engagement instructional strategies and on collaborative group problem solving. A ball at rest in the middle of a flat field is in equilibrium. No net force acts on it. . If you saw it begin to move across the ground, you’d look for forces that don’t balance to zero.. We don’t believe that changes in motion occur without cause.. Please form a group of 2 or 3. Have you thought about working with different people??. Collect Whiteboards and Pens!. Learning Targets. Continue to develop our . conceptual understanding . of an object on an incline.. A plane failure is a . comparatively rare . sight in rock slopes because it is only occasionally that all the geometric conditions required to produce such a failure occur in an actual slope. ..
