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.
Torque spec for injector hold down bolts for 3126 b?
seat exhaust side bolt then torque opposite side to 9 ft/lbs
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.
How do you convert angular rotation into force?
You create a purely 'rotatory force' or torque when you have two forces of equal magnitude but opposite direction pushing or pulling on an object. The greater the forces the greater the torque, and the greater the perpendicular distances between the two forces the greater the torque. Note that because the forces are equal and opposite, the object will not accelerate in any direction. But because there is a perpendicular distance between the forces the object will start to rotate.
When is net force zero but torque is not?
When two forces acting on the same wheel are equal and opposite but applied at different points on the rim.
What is an example when resultant force is zero but resultant torque is not zero?
A couple: 2 parallel forces equal in magnitude, but opposite in direction separated by a distance.
Why almost all helicopters have a small tail rotor at the back?
when the main blade rotates it creates torque and if that torque is not countered by the rear rotor the helicopter will spin out and crash. the helicopters that do not have a rear rotor have another rotor that is the same size moving in the opposite direction
What are damping devices?
due to reflecting torque pointer moves in one direction by due to controlling torque pointer moves in opposite direction therefore pointer oscillate in forward and backward direction.if there is no deflecting torque the device to ensure that the pointer comes to rest quickly with minimum oscillation at its correct reading position is known as damping device...
