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...

Normal Force

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. FORCES on BLOCK 1 Weight force on block 1 by Earth W1E = 0 i + -40 j N  Normal force on block 1 by Surface  N1S = 0 i + 40 j N  Normal force on block 1 by Hand N1H = 16 i...

Centrifugal Force

curve will stay at 12 m/s throughout the entire turn (provided the driver does not brake). The direction of the velocity vector is changing. A force is required in uniform circular motion.Centripetal Force & AccelerationSince an object in motion will travel in a straight line (Newton's First Law) an force must be required to accelerate the mass . This force does not cause a change in velocity as stated in the introduction, but rather it is responsible for the change in direction. The centripetal...

Natural Forces

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...

Forces lab

Abstract: The previous lab explored the effect of gravity on free fall. It was determined that acceleration is always constant under free fall. However, in this lab, acceleration was observed under different forces, other than just gravity. Therefore, depending on how strong the forces being exerted were, acceleration differed. It wasn’t constant anymore. Using a glider on a air track and a pulley, different masses were attached at the end of the string and the glider was allowed to move on the...

Gravitational Force

Universal Gravitation Apples had a significant contribution to the discovery of gravitation. The English physicist Isaac Newton (1642-1727) introduced the term "gravity" after he saw an apple falling onto the ground in his garden. "Gravity" is the force of attraction exerted by the earth on an object. The moon orbits around the earth because of gravity too. Newton later proposed that gravity was just a particular case of gravitation. Every mass in the universe attracts every other mass. This is the...

Shear Force

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...

Force and Acceleration

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)....

Competing forces

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...
