The momentum of an object is given by multiplying its mass and velocity. Momentum is a property of any object that moves with mass. The only difference between angular momentum and linear momentum is that angular momentum deals with moving or spinning ob…

Moment of a Force

The idea of moments is an important concept in physics. It arises from the fact that distance often plays an important part in the interaction of, or in determining the impact of forces on bodies. Moments are often described by their order [first, second…

Chapter 10, Problem 8Q

Figure l0-25b shows an overhead view of a horizontal bar that is rotated about the pivot point by two horizontal forces. F → 1 and F → 2 with F → 2 at angle ϕ to the bar. Rank the following values of ϕ according to the magnitude of the angular acceleration of the bar, greatest first: 90°, 70°, and 110°.

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .

A 1.40 m long uniform bar with a mass O.50 kg is on a horizontal surface and is free to rotate about an axis perpendicular to the page and passing through its left end. A force F of magnitude 10.0N is applied to the bar as shown below. Given that O = 40°, determine the angular acceleration of the bar. Take +z to be out of the page. Pivot 3L/4 +y +z is out of the page +X
