What is the difference between torque and couple?
The turning effect of a force is called torque or moment of the force. SI unit of torque is Newton-Metre. T = FL i.e Torque = Force x Moment arm A couple is formed by two unlike parallel forces of the same magnitude but not along the same line.
How do you find the magnitude in force?
Actually you answer itself is wrong. You can only find the magnitude of force, not the magnitude in force. You can find the magnitude of force by s = (1/2)*a*t^2
Can force change the magnitude of a body?
Yes, force can change the magnitude of a body.
What is the size of a force called?
It is the magnitude of the force applied in Newtons or pounds
A force has both what?
A force is a vector quantity because it has both magnitude and direction.
What 2 things does the moment of a force depend on?
What two factors must be known in order to calculate the moment of a force? Torque = Force * distance Torque and distance must be perpendicular to each other If not you must determine the portion of the torque that is perpendicular.
Deduce an expression for the torque develop by the armature of a dc motor?
he magnitude of torque depends on three quantities: First, the force applied; second, the length of the lever arm[4] connecting the axis to the point of force application; and third, the angle between the two. In symbols:whereτ is the torque vector and τ is the magnitude of the torque,r is the displacement vector (a vector from the point from which torque is measured to the point where force is applied), and r is the length (or magnitude) of the lever arm vector,F is the force vector, and F is the magnitude of the force,× denotes the cross product,θ is the angle between the force vector and the lever arm vector.
How do you calculate braking torque?
To calculate brake torque, multiply force with the distance from the point of rotation. Force is equal to the torsional reaction caused by the brakes, and is also equal in magnitude to the torque exerted by the road.
What is the unit of torque?
the unit of torque is NM.Torque has dimensions of force times distance. Official SI literature suggests using the unit newton metre (N·m) or the unit joule per radian.[8] The unit newton metre is properly denoted N·m or N m.Torque, moment or moment of force is the tendency of a force to rotate an object about an axis.The magnitude of torque depends on three quantities: the force applied, the length of the lever arm[2] connecting the axis to the point of force application, and the angle between the force vector and the lever arm. In symbols:whereτ is the torque vector and τ is the magnitude of the torque,r is the displacement vector (a vector from the point from which torque is measured to the point where force is applied), and r is the length (or magnitude) of the lever arm vector,F is the force vector, and F is the magnitude of the force,× denotes the cross product,θ is the angle between the force vector and the lever arm vector.
What is the turning effect of a force about a point equal to the magnitude of the force times the perpendicular distance from the point to the line of action from force?
That's the torque due to the force.
A force that causes an object to move is a?
Generally just a force. A turning force is called a torque.
What is the formula for torque?
t = r X F, where t is torque, r is displacement, and F is force; all quantities are vectors. Because the formula contains a cross product, the magnitude of the torque is given by the expression rFsin(θ), where θ is the angle between the position vector and the force vector.
What is the difference between torque and couple?

How does torque differ from force?
Torque is the tendency of a force to rotate the body to which it is applied.Torque is always specified with regard to the axis of rotation. It is equal to the magnitude of the component of the force lying in the plane perpendicular to the axis of rotation, multiplied by the shortest distance between the axis and the direction of the force component. Torque is the force that affects rotational motion; the greater the torque, the greater the change in this motion. Whereas,force is the agency that alters the direction, speed, or shape that a body would exhibit in the absence of any external influence.It is a vector quantity, having both magnitude and direction. Force is commonly explained in terms of Newton's laws of motion. All known natural forces can be traced to the fundamental interactions. Force is measured in newtons (N).
When force causes a rotation motion it is called?
I think you are looking for the word 'torque'.
What is a torque meter?
A torque sensor, or torque meter, is a device that measures the torque on rotating systems, usually wheels. Torque, in this case, is the twisting force that causes rotation, such as that applied when you pedal a bicycle.
A planet revole around the sun under the affect of gravitation exerted by the sun why the torque on the planet due to gravitation force is zero?
Because torque is (magnitude of the force) x (distance between the point where the force is applied and the center of rotation). Gravitational force is always directed toward the center of rotation, so the second factor is zero, and the torque is therefore zero.
