Inclination of a Line01:25

Inclination of a Line

The inclination of a line describes its angle of tilt with respect to the horizontal axis. While a line itself is an abstract object with no thickness, its orientation on the Cartesian plane is determined by its slope, which reflects how steeply it rises or falls. The inclination angle, always measured counterclockwise from the positive x-axis, varies between zero and π radians for nonhorizontal lines. This angle directly relates to the slope, providing a geometric interpretation of the...

Torque01:10

Torque

Torque is an important quantity for describing the dynamics of a rotating rigid body. We see the application of torque in many ways in the world, such as when pressing the accelerator in a car, which causes the engine to apply additional torque on the drivetrain. Here, we define torque and provide a framework to create an equation to calculate torque for a rigid body with fixed-axis rotation.
Torque can be considered as the rotational counterpart to force. Since forces change the translational...

Work Done Over an Inclined Plane

The center-of-mass framework helps to easily describe the work done on rigid bodies. Since the internal forces in a rigid body do no work, they can be ignored, and the external forces can be considered in the work-energy theorem.
The work done by gravity to move a rigid body, or the work done by an opposing force to move a rigid body against gravity, can be calculated using the center-of-mass framework. It is the line integral of the force of gravity over the path, considered positive if...

Torque Free Motion01:15

Torque Free Motion

The torque-free motion refers to the movement of a rigid body in space when no external torques are acting upon it. This type of motion can be observed in environments where there are no external forces or frictions, like in outer space. For example, a rotation of Mars in space is a torque-free motion. Mars is an axisymmetric object, meaning it has an axis of symmetry along which it rotates, designated as the z-axis. The rotating frame of reference is defined such that the center of mass of...

Net Torque Calculations01:19

Net Torque Calculations

When a mechanic tries to remove a hex nut with a wrench, it is easier if the force is applied at the farthest end of the wrench handle. The lever arm is the distance from the pivot point (the hex nut in this case) to the person’s hand. If this distance is large, the torque is higher. Only the component of the force perpendicular to the lever arm contributes to the torque. Therefore, pushing the wrench perpendicular to the lever arm is more advantageous. If multiple people apply force to...

Moments of Inertia for an Area about Inclined Axes01:18

Moments of Inertia for an Area about Inclined Axes

In physics and engineering, understanding the moments of inertia for a given area with asymmetrical mass distribution is critical for proper design and analysis. When considering an arbitrary coordinate system, the moments of inertia can be obtained by integrating the moment of inertia for an infinitesimal area element.
