PPT-FORCES AND STRUCTURES Force

the influence that tends to change the speed and direction of a stationary or a moving body  External Forces Internal Forces There are 3 types of Internal forces 1 Compression 2 Tension. Tension, Compression, shear, and Torsion. Mr. Ruddle. Construction Technology. Lesson Overview. In this lesson, you will analyze the four forces that can potentially act upon structural objects: tension, compression, shear and torsion. The lesson will prepare you to be able to select appropriate materials and designs for different situations based on the types of forces that need to be accounted for.. On a post-it, write down anything you know about the word force or the different ways you use the word force.. Scientific Definition. A force is a . push . or a . pull. of an object.. When there is a force, one object is applying a force and on object is receiving the force.. One popular urban myth tells a story of a man who makes a wish from the top of the Empire State Building, then tosses a penny off the roof. Over 1,000 feet below, a pedestrian is hit by the speeding penny and killed. …Good luck, huh?. Objectives. To introduce a truss-structure system. To define truss. To demonstrate the types of trusses . 6 - . 3. Introduction. For the equilibrium of structures . which are . made . up . of several connected parts, the . Topics 4-7. Topic 4: Forces, Loads, and Stresses. Types of Forces. Internal. Tension, compression, shear, torsion, bending. External. Dead Load. Permanent force acting on a structure. Includes the weight of the structure itself. Topics 5& 6. Designing With Forces . Designers often consider:. Load distribution. Directing forces to help the structure. Shaping parts to withstand forces the structure will have to resist. Problem:. Student notes are shown in blue.. Force Defined. Any influence that can cause a change in an object’s motion.. A bat strikes the ball with a force that causes the ball to stop and then move in the opposite direction.. . . Example:. What is a force? . a) Strong . nuclear . force. b) Electromagnetic force. c) Weak force. d) Gravity.. EXAMPLE? an atom . #2) There are four forces that hold all matter together. 3) Gravitational forces . Net Force TEKS ( 8.6)   Science concepts. The student knows that there is a relationship between force and motion. The student is expected to: (A)   demonstrate how unbalanced forces cause changes Expedition 3: Fundamental Forces Forces and Laws of Motion http://webpath.follettsoftware.com/resource/viewurl?encodedUrl=plo2j1Ikxcj5uQozTp-kxdLlZXe3VIeh2JUFcQGT0_Q&version=1&userGUID=41192717-80A3-450C-8DA0-6CF1AC2834B9&gv=1&gc=-17299486&appsignature=Destiny&appversion=11.5.3.0+% Review: Ideas about Friction. What is friction and how does it work? . Are there bumps anywhere else besides . the surface an object moves across?. Give an example of friction from your everyday life. .
