Answer :
If a lever has a constant force applied at 90∘ to the lever arm at a fixed distance from the pivot point (point of rotation), the torque on the lever is given by Torque = force (at 90∘ to lever arm) × distance to pivot point
Force should be perpendicular to the lever arm
Therefore; you would do 15N X 2.0 m = 30 Nm or 30Joules
Therefore; you would do 15N X 2.0 m = 30 Nm or 30Joules
The Torque on the liver from pivot (Point of Rotation) is 30.0 Nm. Which can be calculated by multiplying the Applied force and distance from the pivot.
Further Explanations:
Torque:
The turning effect of force when it is applied on an object is called torque.
Formula:
T = F.d sin (Theta)
Here F is the applied force on the object and d is the distance from the pivot(Point of Rotation).
S.I Unit:
S.I means the units given by the international system.
The S.I unit if torque is “Nm”.
Which can also be get from the formula of torque simply the si unit of force is “N” and od distance is “m” so the whole unit of torque is “Nm”.
Calculation:
Data:
F= 15N, d= 2.0m theta = 90 degree
Solution:
Here we can apply the Formula of Torque as follows:
T = F.d sin (90) here sin (90) = 1.
T = 15N x 2.0m x 1
T = 30Nm (J)
So in this way you can calculate the torque by this formula. By this simple formula you can calculate the torque of all questions. This is very easy to understand Hop you understand how we calculate the torque of any object if its force and distance is given form the pivot(Rotating Point )and its and is at 90 degree
