PPT-Chapter 4 Forces and Moments

Equations of Motion from Chap 3 External Forces and Moments Gravity Force above static pressure below static pressure Airfoil Pressure Distribution Aerodynamic Approximation Control Surfaces Conventional. These intermolecular forces are important for many additional reasons For example solubility and vapor pressure are governed by intermolecular forces The same factors that give rise to intermolecular forces eg bond polarity can also have a profound Let’s take everything we have learned so far and now add in the two other processes discussed in the introduction chapter – . advection and retardation. Solve any way you want. What does advection do?. 11.1: Forces change motion. 11.2: Force and mass determine acceleration. 11.3 Forces act in pairs. 11.4 Forces transfer momentum. Warm-up Questions (T or F). Speed includes direction, while velocity does not. Chapter 13 Strengths. Introduction. Beams are members that carry transverse loads and are subjected to bending. Any member subject to bending is referred to as a beam. Beams considered in this course are limited. Forces. Forces can be thought of as pushes and pulls. Examples. You exert a force on a door to open it (a push). Gravity exerts a force on you which holds you to the surface of the earth (a pull). Forces. Define . forces and different types of forces (push or pull). Measuring . forces in Newtons. Balanced . vs unbalanced forces. Inertia- . what is it and how does it apply to Newton’s first law of motion.. What is pressure?. Pressure is the force per unit area that is applied on the surface of an object.. Chapter 12: Forces and Fluids. Calculating pressure. Pressure increases if the force applied increases and decreases if the area of contact increases.. 02/07/16. Chapter 11: . Intermolecular Forces and Liquids. Chapter 11: . Intermolecular Forces and Liquids. Which type of intermolecular forces have the greatest influence on the following compounds?. .

From the resources slide, click on any resource to see a presentation for that resource.. Changes in Motion. Objectives:. 1. Describe how force affects the motion of an object.. 2. Interpret and construct free-body diagrams.. The Force is Strong With You. Force. is an action exerted on an object which may change the object's state of rest or motion.. Science Question of the Day . What causes the noise when you crack your joints?. _________________________________. _________________________________. _________________________________. Gravity . Gravity is a specific kind of _____________.. . Static Equilibrium: We can use this fact to find the conditions for "static equilibrium": the condition an object is in when there are forces acting on it, but it is not moving. . The conditions for static equilibrium are easy to state: the sum of the (vector) forces must equal zero, and the sum of the torques must equal zero: . Science Question of the Day . What causes the noise when you crack your joints?. Gravity . Gravity is a specific kind of force.. A force is simply the push or a pull on an object.. Can you think of some examples of pushes and pulls on objects?.
