I got the Below Answer from Allinterview.com, I just Reproduced. Bolt and nut combinations need to be "stretched" in order to provide a clamp effect across the joint. "Bolt Torquing" stretches the bolt as the nut is turned by a wrench. The more the nut is turned, the further it rides up the bolt's threads. Since it can't extend into the joint, the nut "pulls" the bolt, thus "stretching" it. "Bolt Tensioning" uses a tensioning tool to pull the bolt until the required stretch has been achieved. The nut is then turned freely by hand until it rests against the joint face. The tensioning pressure is then released. The applied stretch is retained mechanically by the nut. Since friction has an effect on how easily a nut can be turned against a joint's face when torqued, "Torquing" is much less accurate than "Tensioning" (in which friction is moot).

What is the relationship between torque and slip?
Torque in an induction motor is proportional to slip, which is the difference between the synchronous speed and the actual rotor speed. As slip increases, torque also increases, up to a certain point. This relationship is key to understanding the motor's operating characteristics.
What is mean resisting torque in turning moment diagram?
The resisting torque in a turning moment diagram is the torque opposing the applied torque or force, usually due to friction or other resistance in a system. It is represented by the downward curve or line in the turning moment diagram, indicating the counteracting force against the applied torque. The difference between the applied torque and resisting torque determines the net torque or moment acting on the system.
What are some common torque questions that are frequently asked in mechanical engineering interviews?
Some common torque questions asked in mechanical engineering interviews include: What is torque and how is it calculated? How does torque affect the performance of a machine or system? Can you explain the difference between static and dynamic torque? How do you determine the torque required to move a specific load? What factors can affect the torque output of a motor or engine? How do you calculate the torque required for a specific application or task? Can you discuss the importance of torque in mechanical design and analysis? How do you measure and test torque in a mechanical system? Can you explain the concept of torque multiplication and its applications? How do you troubleshoot and resolve torque-related issues in a mechanical system?
What is the relationship between torque and acceleration in the context of the formula for rotational motion?
In the context of rotational motion, torque is directly proportional to acceleration. This means that increasing torque will result in a greater acceleration, and decreasing torque will result in a lower acceleration. The relationship between torque and acceleration is described by the formula: Torque Moment of Inertia x Angular Acceleration.
What is the relationship between torque and the human body?
Torque is the rotational force that can be applied to the human body, such as when lifting weights or performing physical activities. The relationship between torque and the human body is that torque is necessary for movement and stability in activities that involve rotation or twisting motions.
What is the difference between dynamic torque and static torque ratings?
One difference between dynamic torque and static torque is the level of difficulty to measure. Static torque is each to measure, while dynamic torque is not. This is because it requires a transfer of an electric or magnetic effect.
What is the difference between max torque and breakdown torque of a electric motor?
Max torque and breakdown toarque are the same...,.the point at which a motor will stop/stall.
What is the difference between a driver gear and a driven gear?
The driver gear has the input torque, and the driven gear has the output torque.
What is difference between torque at Nm equals 120 rpm equals 1800 and Nm equals 120 rpm equals 4000 give detail better as performance and load capacity in petrol engine?
Difference between Torque and load
What is the difference between an Olds 350 Rocket and a non-rocket?
More bottom end torque!
What is the difference between electromagnetic torque and load torque in electrical machines?
Electromagnetic torque and load torque are different.Electromagnetic torque is the torque that is produced inside the machine which makes the machine rotate,while load torque is the torque that is applied externally with brake drum and and spring balance.Electromagnetic torque can be varied by varying the speed of the machine,but load torque is fixed.
What is the difference between power and torque?
In simple terms, torque gets you moving and power keeps you moving. In other words, your acceleration is dictated by the torque your engine provides and the top speed is limited by the power.
Is the Torque to fasten the same to unfasten?
The torque needed to loosen a bolt or joint is often much higher than the torque needed to put the bolt in in the first place. There is no set value difference between the two, unfortunately.
What is the relationship between torque and slip?
Torque in an induction motor is proportional to slip, which is the difference between the synchronous speed and the actual rotor speed. As slip increases, torque also increases, up to a certain point. This relationship is key to understanding the motor's operating characteristics.
Which is the Indian code for post tensioning?
TR 43 is the Indian code used for post-tensioning
What is ment by the term torque multiplication?
Torque multiplication is proportional to the difference in speed between the impeller and the turbine. for example : At an engine speed of 2100 RPM, and torque at that speed of 100 Newton meters, the torque input to the transmission will be 2.2 times that value - 220 Newton meters with help of torque multiplication.
What is the difference between breakaway torque and rotational torque?
Breakaway torque is the torque required to start the initial movement, in the loosening direction, of a bolt, screw, or nut from its (non−loaded) at rest position with the locking element engaged. Tightening torque is the torque necessary to move the bolt, screw, or nut along its threaded length in the tightening direction.
