Torque, moment of force or moment, is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. In Mathematical, torque is defined as the cross product of the lever-arm distance and force, which tends to produce rotation. Simple speaking, torque is a measure of the turning force on an object such as a flywheel or a bolt.
The complete method for calculating Torque is actually. T (torque) = F (force) * s (distance from pivot) * sin (theta), where theta is the angle between the force and the position vector. In your question theta = 70. So you can just plug in the value to find your answer :-) ( 7 votes) Upvote.
Torque and Angular Acceleration. In translational dynamics, torque or moment is a vector quantity required to rotate an object about a turning point. Mathematically, it is the product of a force acting on a point and the perpendicular distance from the force to the turning point. The torque is measured in Newton-metres, as shown in the equation ...
Torque can be measured using a variety of different units. These include the kilogram-force meter (kgf·m), Newton meter (N·m), and the gram-force centimeter (gf·cm). In the United States, torque is typically measured using pound-force inches (lbf·in), pound-force foot (lbf·ft), and ounce-force inches (ozf·in).
Key Points. When a torque is applied to an object it begins to rotate with an acceleration inversely proportional to its moment of inertia. This relation can be thought of as Newton's Second Law for rotation. The moment of inertia is the rotational mass and the torque is rotational force. Angular motion obeys Newton's First Law.

Jun 18, 2024 · The torque will make the beam rotate clockwise (CW). STEP 2: Since the beam must remain at rest and horizontal, the two torques must cancel each other out. Set up the equation by setting the two torques equal to each other, substitute in your known variables, and solve for F. Your final answer should be F = 90N.
