The lever arm of torque is the perpendicular distance between the pivot point of the object and the line of action of the force applied to it. It determines the effectiveness of the force in rotating an object around its pivot point. A longer lever arm results in greater torque.

Can a force produce a torque when there is no lever arm?
No, a torque is produced when a force is applied at a distance from an axis of rotation. If there is no lever arm (distance from the axis of rotation), the force will not create a torque.
How does the lever arm work?
The lever arm is the perpendicular distance between the pivot point of a lever and the line of action of a force applied to it. It determines the torque produced by the force acting on the lever. A longer lever arm results in a greater torque for the same amount of force applied.
What is the torque of a force of 17 N with a lever arm of 2.6 m?
The torque can be calculated using the formula: torque = force * lever arm. Therefore, the torque will be 17 N * 2.6 m = 44.2 Nm.
Where should a force be applied to a lever arm to produce the most torque?
A force should be applied at the end of the lever arm farthest from the fulcrum to produce the most torque. This maximizes the lever arm length, resulting in a greater moment arm for the force and thus higher torque.
How may the torque of a given force be increased?
To increase the torque of a given force, you can increase the distance from the pivot point (lever arm). This is because torque is the product of force and lever arm length. Increasing either the force or the lever arm length will increase the torque.

No, a torque is produced when a force is applied at a distance from an axis of rotation. If there is no lever arm (distance from the axis of rotation), the force will not create a torque.

The product of force and lever-arm distance in producing rotation is?
The product of force and lever arm distance in producing rotation is torque. Torque is a measure of the rotational force applied to an object and is calculated by multiplying the force applied by the lever arm distance at which the force is applied.
How it is possible for a large force to produce only a small or even zero torque?
A large force can produce a small or zero torque if the force is applied at a point where the lever arm (distance from the point of rotation to the line of action of the force) is very small or zero. Torque is calculated as force multiplied by lever arm, so a small lever arm can result in a small or zero torque even with a large force.
What is the effect of the length of a lever arm in the pull force?
The longer the lever arm, the less force is required to move an object because the longer lever arm provides a mechanical advantage. This is based on the principle of torque, where force is multiplied by the lever arm length to produce rotational motion.
Where would place a fulcrum of a lever if you had to lify a heavy load?
A fulcrum would be placed as close to the heavy load as possible. This minimizes the lever arm (and thus minimizes the torque) for the load while maximizing the lever arm (and thus maximizing the torque) for the force you must apply.
How does a large force produce a small torque and it is possible for a small force to produce a large torque?
A large force produces a small torque when it is applied close to the axis of rotation, resulting in a smaller lever arm. Conversely, a small force can produce a large torque when applied farther from the axis of rotation, creating a larger lever arm which amplifies the effect of the force. This relationship is described by the equation torque = force x lever arm, so increasing the lever arm can compensate for a smaller force to generate a larger torque.
In what direction should a force be applied to produce maximum torque?
A force should be applied perpendicular to the lever arm to produce maximum torque. This means applying the force at a 90 degree angle to the direction of the lever arm or the radius of the rotation.
What is the moment arm of resistance?
The moment arm of resistance refers to the perpendicular distance from the line of action of a resisting force to the axis of rotation. It helps determine the torque generated by the resistance force on a lever or rotating object. A longer moment arm increases the torque generated by the resistance force.
