Why is torque maximum when angle is 90 degrees?
The direction of the torque is given be the right hand rule, which gives a vector out toward the reader in this case. Note that the torque is maximum when the angle is 90 degrees. That is, it is along the rotation axis in the direction out of the screen.
What is r in torque?
The magnitude τ of the torque is given by. where r is the distance from the axis of rotation to the particle, F is the magnitude of the force applied, and θ is the angle between the position and force vectors.
How do you find the torque of an object?
Torque is the twisting force that tends to cause rotation. The point where the object rotates is known as the axis of rotation. Mathematically, torque can be written as T = F * r * sin(theta), and it has units of Newton-meters.
What is torque angle?
Put into its most simple terms, torque angle replaces a maximum torque value for a fastener with a specific amount of fastener rotation. After setting a low baseline torque, just to make sure the fastener is set, the fastener is rotated a precise amount to set the final position and clamp load.
Is moment F Cross R or R cross F?
The moment vector of the force F about point A will be equal to the cross products of the r vector and the force vector. The r vector is a vector from point A to any point along the line of action of the force. It is important to note here that all quantities (r, F and M) are vectors.
How does angle affect torque?
The magnitude of the torque depends on: Radius r: Increasing the radius increases the torque. Angle between the force and lever arm θ: Directing a force perpendicular to the lever arm increases the torque.
At what angle is torque maximum?
90º
Maximum torque occurs when θ = 90º and sin θ = 1.
How do you calculate torque from R and F?
The magnitude of a torque about a fixed axis is calculated by finding the lever arm to the point where the force is applied and using the relation |→τ|=r⊥F | τ → | = r ⊥ F , where r⊥ is the perpendicular distance from the axis to the line upon which the force vector lies.
