Torque depends on the force's direction:
* Torque = Force x Distance x sin(theta)
* Force: The applied force (15N in your case)
* Distance: The distance from the axis of rotation to the point where the force is applied. In this case, it could be the radius of the disk (0.5m).
* theta: The angle between the force vector and the line connecting the axis of rotation to the point of force application.
Example Scenarios:
1. Force applied tangentially to the disk's edge: If the force is applied perpendicular to the radius (theta = 90 degrees, sin(90) = 1), then the torque would be:
* Torque = 15N * 0.5m * 1 = 7.5 Nm
2. Force applied at an angle: If the force is applied at an angle to the radius, you need to know the angle to calculate the torque.
In summary: You need to know the angle at which the force is applied to the disk to calculate the torque.
