What is A force of 8 N that is applied 0.5 m from a doors hinge makes an angle of 45 with the door What is the torque exerted by the force?

The torque exerted by a force is calculated by multiplying the force by the distance from the pivot point and the sin of the angle between the force and the lever arm. In this case, the torque exerted by the force would be 8 N * 0.5 m * sin(45 degrees) = 2.83 Nm.


Why torque produce by centripetal force is zero?

The torque produced by centripetal force is zero because the force is acting perpendicular to the radius of rotation. Torque is calculated as the force multiplied by the distance from the axis of rotation, and when the force and distance are perpendicular to each other, the torque becomes zero.


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.


Define torque.derive its unit?

Torque is vector energy. Physicists have mistakenly defined energy as a scalar. Energy is a quaternion consisting of scalar energy (potential) and vector energy (torque). The units of torque is Joules or Newton meter, the same as work or energy..Here is the correct definition of Energy = FD = -F.D + FxD where F is force vector in Newtons and D is displacement vector in meters.F.D = - FDcos(Angle) is the Work or scalar energy and FxD=FDsin(Angle) is the Torque or vector energy. If the angle between the force and displacement is 90 degrees there is only torque; if the angle is a zero degrees there is only work or scalar energy ; if the angle is not a multiple of these two angles there is both scalar and vector energy; work and torque. E.g FD= -Fdcos(45) + Fd sin(45) gives work and torque.


Why are trigonometry functions periodic?

Because any angle increased by k*2pi radians (= k*360 degrees) where k is an integer, is, effectively, the same angle. This implies that f(x + 2kpi) = f(x) for any angle x and any trig function f. This gives f a maximum period of 2pi radians.


What is the name of this formula Torque F D k?

I don't think it's a special name, but it looks similar to the definition of torque. To be precise, torque is the product of the force, the distance from the axis of rotation, and the since of the angle.


Deduce an expression for the torque develop by the armature of a dc motor?

The torque developed by the armature of a DC motor can be expressed as: T = k * Ia * Φ where T is the torque, k is a constant factor, Ia is the armature current, and Φ is the magnetic flux in the motor.

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 angle of separation?

It is the angle between the rays from two points to a reference point. For example, if you can see a dog (D) in the background and your friend (F) in front of you, the angle of separation between the dog and your friend, as seen from your eye (E), is the angle DEF. The angle of separation between the same things, from someone else's viewpoint will be different.


How do you convert torque into axial load?

Torque=.2*F*Bolt Maj. Dim. F=axial force


What factors affect the magnitude of torque?

The magnitude of torque is affected by the force applied and the distance between the point of rotation and the point where the force is applied. Increasing force or increasing distance from the point of rotation will increase the magnitude of torque. Additionally, the angle at which the force is applied relative to the lever arm can also affect the torque.
