What else can I help you with?
Is it possible for torque to have a negative value?
Yes, torque can have a negative value when it causes a rotational force in the opposite direction.
Do internal forces which are equal and opposite to each other exert torque?
Yes. Since torque is F x R, even if two forces are equal and opposite they point where they are applied may lie at different distances from the axis of rotation thus resulting in a net torque.
When is torque negative in a mechanical system?
Torque is negative in a mechanical system when the force applied causes the object to rotate in the opposite direction of the desired motion.
Torque spec for injector hold down bolts for 3126 b?
seat exhaust side bolt then torque opposite side to 9 ft/lbs
What are the differences between positive and negative torque in mechanical systems?
Positive torque in mechanical systems causes rotation in one direction, while negative torque causes rotation in the opposite direction. Positive torque is typically associated with tightening or accelerating, while negative torque is associated with loosening or decelerating.
What is inertia torque?
Inertia torque an imaginary torque, which when applied upon a rigid body, brings it in an equilibrium position. Its magnitude is equal to accelerating couple, but opposite in direction.T1 = -IαwhereI = mass moment of inertia of body andα = angular acceleration
Why do cranes not fall forwards when lifting heavy weights?
It's because torque caused by gravity creates rotation around of the base of the crane. And the torque created by the counter mass is opposite in direction but not large enough to compensate torque caused by gravity.
How counter propellors work?
Counter-propellers (proper name contra-rotating propellers) work by spinning in opposite directions. This cancels out torque in the same way as a helicopter uses rotors to cancel torque.
The torque reaction and the newton second law are same?
Its Not the second law but the third law which says 'for every action there is an opposite and equal reaction.' Torque reaction is observed in helicopters motion. As the main motor rotates (that is the wings on the top), the helicopter itself tries to rotate(the opposite direction) in order to give an equal and opposite reaction. For this reason, a tail rotor ( a motor) is kept in the vertical direction towards the end of the copter so that it balances the torque produced by the helicopter ( which not to forget, was produced in order to satisfy newtons third law )
What is tension and torque have to do with bridges?
Torque is used in bridges to lift a portion of it up, right! Well at the hinges the machine applies a force outwards and by newtons's third law of motion their will exist another equally opposite force on the other side of the bridge. Thus the torque develops.
If you hang a meterstick in balance and then hang a 100g mass on either side of the meterstick at equal distances maintaining the balance of the meterstick what is the net torque on the system?
The net torque on the system is zero because the meterstick is in equilibrium. The torque created by the 100g mass on one side is equal and opposite to the torque created by the 100g mass on the other side, preventing the meterstick from rotating.
What is reaction torque?
Reaction torque is the torque that arises in response to an applied torque on a system, adhering to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. It occurs when an external force or moment is applied, causing a rotational effect on an object, leading to a counteracting torque that opposes the applied one. This concept is crucial in mechanical systems, such as engines and gears, where it helps to maintain balance and stability. Reaction torque is essential for understanding the dynamics of rotating bodies and ensuring proper design and operation of mechanical systems.
