PPT-Pendulum without friction

Limit cycle in phase space no sensitivity to initial conditions Pendulum with friction Fixed point attractor in phase space no sensitivity to initial conditions Pendulum with friction basin of attraction. ME 225 ; PRINCIPLES OF TRIBOLOGY. PRESENTATION ON. SIDDAPPAJI .B. FRICTION. A force that resists the relative motion or tendency to such motion of two bodies in contact. . Friction always works in the direction opposite from the direction the object is moving, or trying to move. . Surya Tahir/BTEC National Diploma/Pendulum Experiment. Covers objectives:. P3 – demonstrate the ability to plot a linear graph using scientific data. P3 – Calculate the rate of change by the most appropriate method. m. hanging from a light (massless) string of length . L. . The pendulum undergoes small oscillations, and can be considered to be undergoing simple harmonic motion. If the mass of the point mass is changed to 4.

Use the . magnitude. of gravity (9.8 m/s. 2. ). Example . 8. A mass (m = 5.67 kg) is attached to a rope with a length of 0.950 m. . Physical pendulums take into account mass distribution, friction, air resistance. The force that pulls the mass back towards equilibrium is the . restoring force. Pendulums. If the restoring force is proportional to the displacement, then the pendulum’s motion is simple harmonic. Friction is the resistance to the sliding, rolling, or flowing motion of an object due to its contact with another object. . When a moving object comes in contact with another object, friction is the opposing force that slows or stops the moving object. . What factors affect (the size of) friction?. Survey says:.
