Key Concepts

Torque

Torque is a measure of the rotational effect of a force applied to a lever or an object about a pivot point. It is defined as the product of the force magnitude and the perpendicular distance (the moment arm) from the pivot to the line of action of the force.

Moment Arm

The moment arm is the shortest distance from the axis of rotation to the line along which the force acts. It is crucial in determining the magnitude of the torque, as only the component of the force perpendicular to the lever contributes to the torque.

Net Torque

Net torque is the sum of all individual torques acting about a point, taking into account the direction (clockwise or counterclockwise) of each torque. It determines the overall tendency of an object to undergo angular acceleration about the axis of rotation.

Right-Hand Rule

The right-hand rule is a convention used to determine the direction of the torque vector (or the angular momentum vector) resulting from a given force. It involves pointing the fingers of the right hand in the direction of the moment arm and curling them toward the force direction; the thumb then points in the direction of the resulting torque.

00:01 Will come true for a number ten point to check.

00:03 Pretend dynamic suffered is no emotion.

00:06 So we in this problem can point to were given a road.

00:12 So this is a road and this is a fixed point if one have to force acting on this route.

00:18 So this one is f one force and this one you have to force after forces acting two meter apart, a touch of degree and this afghan forces acting downward and the end of this so totally distance from this point, the fixed point and the f one force where is acting is five meter and therefore no distance between enough to force and the point which is fixed.

00:43 It's too meter.

00:45 That's why we have f one equals two eight newton, which is equal to a dude in here and after it because to tell you two are running close to five meters, our two physical sue to mito two down one angle is the angle between r and f, which is decided by this.

01:04 So we have our that this way and everyone working this week.

01:10 So my angle is because too this angle which is to seventy degree not talking about this angle.

01:17 So this angle is again.

01:19 So this is my art director, and this is my half director.

01:22 So angle is this just because two one fifty illegally.

01:26 So again.

01:27 So we have, like, this way after you acted this way, dangle is one fifty and this angle is thirty degree.

01:40 And for every force we have arwa nectar which has land five meter and forces acting this way.

01:51 So my angle is this much.

01:53 It is to central italy and now we have used this formula two articles to r cross f, the cross product off our weapon affected.

02:02 So which is it caused to our f scientist with ties? the angle between r and f and the angle is between are in f is taken clockwise, anti clockwise.

02:15 So it yet auntie clockwise and them...
