perpendicular to the directrix and passing through the focus (that is‚ the line that splits the parabola through the middle) is called the "axis of symmetry". The point on the axis of symmetry that intersects the parabola is called the "vertex"‚ and it is the point where the curvature is greatest. The distance between the vertex and the focus‚ measured along the axis of symmetry‚ is the "focal length". The "latus rectum" is the chord of the parabola which is parallel to the directrix and passes through

always be in a specified chosen axis of rotation. The point of motion is basically defined as the relationship between mass and the perpendicular distance to the rotational axis. KEYWORDS: Moment of Inertia‚ Rigid body‚ Angular motion‚ Axis of rotation Introduction Moment of inertia is always defined with respect to a specific axis of rotation. The mass moment of inertia with respect to an axis is also defined as the product of the mass times the distance from the axis squared.

All cross-sections remain plane and perpendicular to longitudinal axis. Bending in beams Key Points: 1. Bending moment causes beam to deform. 2. X = longitudinal axis 3. Y = axis of symmetry 4. Neutral surface – does not undergo a change in length Consider the simply supported beam below:

The mean electrical axis gives us the direction of the repolarization or depolarization. To determine the mean electrical axis‚ first two leads or needed from an ECG. The S wave height is subtracted from the Q wave height‚ which subtracted from the R wave height. This is to be performed for both‚ or every lead. Resulting values are plotted as horizontal lines on the graph. The zero point is determined by the intersection of all the leads. A line is then drawn through the axis of these points‚ perpendicular

The shift of German tanks led straight into Operation Supercharge. This phase of the battle began on November 2‚ flanking the Axis forces with the southern units with the objective of destroying enemy armor‚ forcing the enemy to fight the Australian infantry from the north and the British/American tanks from the south. Operation Supercharge was later seen as the decisive point that defeated the lauded General Rommel. Montgomery also received intelligence regarding the vulnerability of the German
