Sure, here are the step by step solutions:
To resolve a line into its parallel and perpendicular components:
- Draw a line parallel to passing through the point where you want to resolve it.
- Draw a line perpendicular to passing through the same point.
- The intersection of with gives the parallel component.
- The intersection of with gives the perpendicular component.
To show that the parallel component of does not produce any torque:
- Torque is produced by a force acting at a distance from the pivot point.
- The parallel component of acts along the line passing through and , and therefore does not create any distance from the pivot point.
- Therefore, the parallel component of does not produce any torque.
To calculate the torque produced by the perpendicular component of :
- The torque produced by a force is given by the formula , where is the distance from the pivot point, is the force, and is the angle between the force and the line passing through the pivot point.
- In this case, the distance is equal to the length of the perpendicular component of .
- The force is equal to the weight of the object, which is .
- The angle is equal to 90 degrees, since the force acts perpendicular to the line passing through the pivot point.
- Substituting these values into the formula, we get .
To calculate the value of :
- We are given the formula .
- Rearranging the formula, we get .
- Substituting the given values, we get .
- Simplifying this equation, we get .
Therefore, the torque produced by the perpendicular component of is , and the value of is .
