questions: force and motion I problem 1 The figure below is an overhead view of a 12 kg tire that is to be pulled by three ropes. One force (Fl‚ with magnitude 50 N) is indicated. Orient the other two forces F2 and F3 so that the magnitude of the resulting acceleration of the tire is least‚ and find that magnitude if (a) F2 = 30N‚ F3= 20 N; (b) F2= 30 N‚ F3 = 10 N; and (c) F2 = F3 = 30 N. problem 2 A weight-conscious penguin with a mass of 15.0 kg rests on a bathroom scale (see figure below).

CEMB 121 MECHANICS OF MATERIALS LABORATORY EXPERIMENT (NO.2 (a)) SHEAR FORCE I SUMMARY Shear Forces occurs when two parallel forces act out of alignment with each other. For example‚ in a large boiler made from the sections of sheet metal plate riveted together‚ there is an equal and opposite force exerted on the rivets‚ owing to the expansion and contraction of the plates. The shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of

How competitive forces shape strategy Pflicht 4. (5Forces) " 1 von 3 While one some- times hears executives complaining to the contrary‚ intense competition in an industry is neither coincidence nor bad luck. Moreover‚ in the fight for market share‚ competition is not manifested only in the other players. Rather‚ competition in an industry is rooted in its underlying economics‚ and competitive forces exist that go well beyond the established combatants in a particular industry. Customers

Types of Forces Used in Basketball Forces are found everywhere‚ but of course‚ you can`t see them. They act on you for example if you are waking there are many forces that act`s on you. If they are not involved you can`t wake. Let`s talk about the forces that are involved in basketball. Basketball is a very enthusiastic sport and you must try it‚ you are not going to regrets. Basketball has original thirteen rules‚ but I am just going to mention 10 of them. 1- The ball can be thrown in any direction

Definition of Force A force is a push or pull upon an object resulting from the object’s interaction with another object. Whenever there is an interaction between two objects‚ there is a force upon each of the objects. When the interaction ceases‚ the two objects no longer experience the force. Forces onlyexist as a result of an interaction. Velocity‚ Acceleration‚ Momentum‚ and Impulse Velocity‚ in physics‚ is a vector quantity (it has both magnitude and direction)‚ and is the time rate of

TITLE : Shear Force Variation with an Increasing Point Load. INTRODUCTION: SHEAR FORCE The shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side of the section to slide or shear laterally relative to the other portion. The diagram shows a beam carrying loads . It is simply supported at two points where the reactions are Assume that the beam is divided into two parts by a section XX The resultant of the loads and reaction acting on

the right on block 1 with a normal force of 16 N. On a sheet of paper‚ draw the free body diagram for block 1 using the two-subscript notation from class. After completing the free body diagram‚ enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component.

HYDROSTATIC FORCE (EXPERIMENT 1) INTRODUCTION The determination of force which are exerted by liquid which are at rest on surface immersed in liquids. From the study by hydrostatic‚ the following principles have been established : a) There are no shear stress present when the fluid is not in motion. b) The pressure exerted by a fluid under hydrostatic conditions. This pressure acts perpendicular to an immersed surface. c) Hydrostatic pressure various linearly‚ increasing with an

Natural Forces A natural force is a power brought on by nature. Natural forces‚ unlike those of other powers‚ are uncontrollable. When a hurricane passes along the coast‚ a bolt of lightning strikes a rooftop‚ and a volcano erupts‚ these are all examples of natural forces. Natural forces can have devastating effects on wildlife‚ humans‚ and the earth itself. Our effects to resist these occurrences‚ our only way to cope with such devastating forces of nature are to observe‚ learn‚ and prepare
