What actually is tension
Himal kharel said:What actually is tension
No, if you are holding the book with a flat hand under it, there is NO "tension" on the book. I agree with LSOS- "tension" is specifically a force that tends to pull something apart. For example if you have a weight suspended from the ceiling by a cable, the weight exerts a force on the cable downward, the attachment to the ceiling exerts a force upward- the cable is under tension.Rayquesto said:A force that opposes all other forces is what I would think. Suppose you are holding a book, so that it becomes at rest. The tension is your force holding it, because you are opposing all other forces affecting the acceleration of the book. In the case of holding the book, the only force affecting the book is gravitational force. So, you are opposing gravitationa force (putting tension on the book) equal to the gravitational force so that it won't accelerate either down or up. If you opposed force more than the gravitational force of the book, then it would start accelerating upward for sometime.
Tension is a force that occurs when two objects are pulled in opposite directions, causing them to stretch or become elongated. It is also known as a pulling force and is typically measured in units of Newtons (N).
Tension and compression are both types of forces that act on objects, but they have opposite effects. While tension pulls objects apart, compression pushes them together. Tension occurs when forces act in opposite directions, whereas compression occurs when forces act in the same direction.
Tension is caused by the interaction between two objects that are being pulled in opposite directions. This can be due to the weight of an object, the force of gravity, or external forces applied to an object.
Tension plays a crucial role in many aspects of everyday life. It is what allows bridges and buildings to withstand heavy loads, and it is also what allows our muscles to contract and produce movement. Tension is also important in sports, such as when a baseball player throws a ball or a weightlifter lifts a barbell.
Tension is studied in science through the laws of physics, specifically Newton's laws of motion. Scientists use mathematical equations to calculate tension in different situations, such as calculating the tension in a rope or cable. Tension is also an important concept in engineering and is studied to design structures and machines that can withstand various forces.
