Understanding Mechanical Advantage in the Single Sheave Pulley
... In order to understand the source of this much-desired mechanical advantage, we need to review an earlier concept. Remember this one? Fundamental Concept 1: In a theoretical, frictionless system, a pulley equalizes the tension in both legs of the rope that passes through it. In the real world, the s ...

Ch. 7 Newton`s Third law of Motion Action and Reaction powerpoint
... 7.5 Defining Systems think! Suppose a friend who hears about Newton’s third law says that you can’t move a football by kicking it because the reaction force by the kicked ball would be equal and opposite to your kicking force. The net force would be zero, so no matter how hard you kick, the ball won ...

PHYS 1443 – Section 501 Lecture #1
... A one piece cylinder is shaped as in the figure with core section protruding from the larger drum. The cylinder is free to rotate around the central axis shown in the picture. A rope wrapped around the drum whose radius is R1 exerts force F1 to the right on the cylinder, and another force exerts F2 ...

The Modified Theory of Central-Force Motion Edison A. Enaibe,(Ph.D.)
... The number of independent ways in which a mechanical system can move without violating any constraints which may be imposed is called the number of degrees of freedom of the system. The number of degrees of freedom is the number of quantities which must be specified in order to determine the velocit ...

3 Newton`s First Law of Motion—Inertia
... We know that Earth pulls on the moon. Does the moon also pull on Earth? If so, which pull is stronger? Answer: Asking which pull is stronger is like asking which distance is greater—between New York and San Francisco, or between San Francisco and New York. The distances either way are the same. It i ...

4.3 Centripetal Acceleration
... sideways acceleration because you and the car are changing direction. The sharper the curve and the greater your speed, the more noticeable this acceleration will become. In this section we examine the direction and magnitude of that acceleration. Figure 1 shows an object moving in a circular path a ...
