What will be the direction of moment of force if the direction of force is reversed?

Direction of force remains same.

Does torque have magnitude and direction?

Torque has both magnitude and direction. (a) A counterclockwise torque is produced by a force →F acting at a distance r from the hinges (the pivot point).

Why torque is equal to R cross F?

Because torque is a kind of moment. So when u apply a force in outer most layer of a shaft or twist a shaft with one end fixed, the force you given multiplied by the distance from out most layer to centre of the shaft. So torque is equal to force x perpendicular distance.

What is the r in torque?

Torque is a measure of how much a force acting on an object causes that object to rotate. The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by ‘r’.

When we change either the direction or the magnitude or both of the applied force its effect?

Also, if the direction or the magnitude of the applied force changes, its effect also changes. In general, more than one force may be acting on an object. However, the effect on the object is due to the net force acting on it.

What is dimensional formula for torque?

ML2T−2.

What does the magnitude of torque depend on?

The magnitude of the torque depends on the force, the direction of the force, and where the force is applied. The magnitude of the resultant vector is r F sin(θ). r is measured from the axis of rotation to the line of the force, and θ is the angle between r and F.

Is torque F Cross R or R cross F?

A particle is located at position r relative to its axis of rotation. When a force F is applied to the particle, only the perpendicular component F⊥ produces a torque. This torque τ = r × F has magnitude τ = |r| |F⊥| = |r| |F| sin θ and is directed outward from the page.

How do you find the magnitude and direction of torque?

Torque Calculation A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force. and the magnitude of the torque is τ = N m.

How do we define the direction of torque?

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. The torque is in the direction of the angular velocity which would be produced by it in the absence of other influences.

When two forces act in opposite directions then net force acting is the?

The net force acting on an object is the combination of all of the individual forces acting on it. If two forces act on an object in opposite directions, the net force is the difference between the two forces.

What is the direction of torque?

Torque is a vector quantity, meaning it has both a direction and a magnitude. Torque is the measure of how much a force acting on an object causes it to rotate. It is the ‘twisting force’ that causes a body to rotate. The point or line about which a body rotates is called the axis of rotation.

What is the formula for torque?

Torque is calculated with respect to (about) a point. Changing the point can change the torque’s magnitude and direction. I. Torque II. Angular momentum – Vector quantity. l r p m(rv) Direction: right hand rule. Magnitude: l = r⋅ psin ϕ= r⋅m⋅vsin ϕ= r⋅m⋅v⊥ = r⋅ p⊥ = (rsinϕ)p = r⊥ p = r⊥m⋅v

Is torque a vector or scalar quantity?

While R, Python, and SQL are arguably the top 3 most essential tools to learn as a d(Continue reading) 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.

Why is torque equal to Force X perpendicular distance?

Because torque is a kind of moment. So when u apply a force in outer most layer of a shaft or twist a shaft with one end fixed, the force you given multiplied by the distance from out most layer to centre of the shaft. So torque is equal to force x perpendicular distance. 8 clever moves when you have $1,000 in the bank.
