What is the perpendicular distance from the axis of rotation to the force vector?
lever arm The perpendicular distance from the axis of rotation (or pivot) to the "line of action" of the force F is called the "moment arm" (sometime, the "lever arm"). Draw a vector r from the axis of rotation to the location of the force F.
What is the perpendicular distance between the force and the turning point if a force of 25 N produces a moment of force of 125 nm?
5 Nm )/( 25 N) = 0.5 m. `
What is the perpendicular distance of force?
In this case, the perpendicular distance is the length of the bar and the torque is equal to the product of the length and the force. In Example 2, the same force is applied to the arm, but the force now acts right through the pivot. In this case, the distance from the pivot perpendicular to the force is zero.
Why is torque perpendicular force?
Torque is inherently a vector quantity. Part of the torque calculation is the determination of direction. The direction is perpendicular to both the radius from the axis and to the force. It is conventional to choose it in the right hand rule direction along the axis of rotation.
What is torque and equilibrium?
A torque is a vector quantity which means that it has both a magnitude (size) and a direction associated with it. If the size and direction of the torques acting on an object are exactly balanced, then there is no net torque acting on the object and the object is said to be in equilibrium.
What is the relation between moment of the force about a and the perpendicular distance from A?
The turning effect of a force is known as the moment. It is the product of the force multiplied by the perpendicular distance from the line of action of the force to the pivot or point where the object will turn. The SI unit of moment of a force is Newton-metre (Nm).
What is the perpendicular distance between the point of application of force and turning point if a force of 2.5 Newton produces a moment of force 1.75 Newton Metre?
Explanation: formulas. now 2.5*1.75. now you are going to that answer is 4.375.
What is the shortest distance between the starting and ending positions of the point where the force is applied?
Displacement is the shortest distance between the initial and final positions of the object.
Why do we measure perpendicular distance?
We can use this to determine the distance between a point and a line in two-dimensional space. We want this to be the shortest distance between the line and the point, so we will start by determining what the shortest distance between a point and a line is.
Why is torque perpendicular to the axis of rotation?
A torque is a force applied to a point on an object about the axis of rotation. The size of a torque depends on (1) the size of the force applied and (2) its perpendicular distance from the axis of rotation (which depends both on the direction of the force plus its physical distance from the axis of rotation).

What is a rotational equilibrium?
Rotational equilibrium is defined as the state of a system for which the total angular acceleration is zero. Since it is the torque which is responsible for this Page 2 2 acceleration, a total torque of zero is also required for a system to be in rotational equilibrium.
What is translational equilibrium in physics?
1) Translational equilibrium: If the net force acting on a body is zero, then the body is said to be in translational equilibrium. In such a case, the center of mass of the body remains either at rest or moves rectilinearly with constant velocity.
When force is perpendicular with the distance between fulcrum and the line of action of force?
Moment of Force The moment of the force is equal to the product of the magnitude of the force and the perpendicular distance of the line of action of the force from the axis of rotation or fulcrum. The SI unit of a moment is Nm but Ncm is also in use.

How do you find the perpendicular distance between the point of an application of a force and a turning point?
ForceF = 80NPerpendicular distance = 1.75m∴ Moment of force = F x perpendicular distance= 80 x 1.75 = 140Nm. What is the perpendicular distance between the force and the turning point if a force of 25 N produces a moment of force of 12.5 Nm ?
Which of the following describes the shortest distance between the initial position and the final position of an object class the direction to where the object is moving too?
Displacement: Displacement is the shortest distance between an object's original and final positions.
Why displacement is the shortest distance?
Explanation: We know distance is the measure of the total length of path transversed by the body. And displacement is the shortest distance from the initial point to the final point. So, we can say that displacement cannot be greater than the distance travelled by the body.
How do you find the perpendicular distance?
That is, to find the distance between two perpendicular lines, we use these steps:
- Find the distance between the intersection of the lines and each of the given points on the lines; call them a and b.
- To find the distance between the two points (c) use the Pythagorean Theorem, a2 + b2 = c2, and solve for c.

What is perpendicular to the axis of rotation?
The vector →r is always defined to be perpendicular to the axis of rotation and to go from the axis of rotation to the point where the force →F is exerted, as illustrated.
What is rotation axis torque?
Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label 'O'.
What is meant by perpendicular distance in physics?
The shortest distance of a point from a plane is said to be along the line perpendicular to the plane or in other words, is the perpendicular distance of the point from the plane.
How do you find the perpendicular distance from the origin?
Where (x′,y′) are coordinates of the point. Since you want distance of line from origin, the coordinates become (0,0) and hence the perpendicular distance of a line from origin is |Ax′+By′+c√A2+B2|=|0+0+c√A2+B2|=|c√A2+B2|.
What is torque and rotational equilibrium?
Then, each force will cause a torque. The net torque is the sum of the individual torques. Rotational Equilibrium is analogous to translational equilibrium, where the sum of the forces are equal to zero. In rotational equilibrium, the sum of the torques is equal to zero.
What is translational and rotational equilibrium?
Translational Equilibrium An object is in translational equilibrium (its momentum is constant) if the sum of the forces acting on it is zero. S Fx = 0. S Fy = 0. S Fz = 0. Rotational Equilibrium An object is in rotational equilibirum (its angular momentum is constant) if the sum of the torques acting on it is zero.
What is the difference between static and translational equilibrium?
static equilibrium: The state in which a system is stable and at rest. To achieve complete static equilibrium, a system must have both rotational equilibrium (have a net torque of zero) and translational equilibrium (have a net force of zero). translational equilibrium: A state in which net force is equal to zero.
What happens when the distance between the fixed point and the line of action of force is decreased?
A decrease in distance between the fixed point and the line of action of the force will lead to a decrease in torque.
What is moment equilibrium?
We consider the equilibrium of an object like a horizontal bar. In the lab it will be a meter stick. Equilibrium means that it does not have translation (motion in which all points on the body move with the same vector velocity) or rotation.

What is moment of a force about a point?
The moment of a force about a point is (the magnitude of the force) × (the perpendicular distance of the line of action of the force from the point).
