INTRODUCTION : Conditions for Rigid-Body Equilibrium The rigid body in figure (a)‚ which is fixed in the x‚ y‚ z‚ reference at constant velocity. A free-body diagram of the arbitrary ίth particle of the body is shown in figure (b). There are two types of forces which act on it. The resultant internal forces‚ f ‚ is caused by interaction with adjacent particles. The resultant external forces F represents‚ for example‚ the effects of gravitational‚ electrical‚ magnetic‚ or contact forces between

Stuart Partner’s Name: Shanygne Swann Lab Report #2 Title of Experiment: Static Friction and Limiting Equilibrium Brief Theory of Experiment: In limiting equilibrium‚ the sum of the forces on block X and on the hanging masses (load) Y is zero. The load is increased to a value until block X just slides at constant speed when the table is tapped. Tapping the table destroys the limiting equilibrium condition momentarily by altering the balance between tension (T) in the string and the maximum

1. Introduction When we say equilibrium‚ it is a state of balance. It is a condition where there is no change in the state of motion of a body. Equilibrium also may be at rest or moving within a constant velocity. A simple mechanical body is said to be in equilibrium if no part of it is accelerating‚ unless it is disturbed by an outside force. Two conditions for equilibrium are that the net force acting on the object is zero‚ and the net torque acting on the object is zero. Thus‚ the following objectives

1.0 ) THEORY (I) Static Stability of Floating Body Referring to Figure 1‚ the weight W of the floating body passes through its center of gravity G. The upthrust or buoyancy force FB acting on the floating body passes through the center of buoyancy B‚ which corresponds to the centroid of the displaced fluid. When the floating body is subjected to a small angular displacement or perturbation θ about its equilibrium upright configuration‚ the center of buoyancy shifts from B to B’‚ while the center
