If the stone is moving at a constant speed and gravity is neglected, the inward-pointing string tension is the only force acting on the stone. If the string breaks, the stone, because of inertia, will keep on going in a straight line tangent to its previous circular path; it does not ...

Under ordinary circumstances, if you pound on a ball with your fist, it’s going to fly straight in that direction.But when you smash a tetherball, the tension of the string acts as a centripetal force that redirects it along the perimeter of a circle, of which the pole acts as a ...
Newton's Third Law of Motionrelates to interactions between two objects. It says that for every action there is an equal and opposite reaction. When a force is applied to one object, it has the same effect on the object that produced the force but in the opposite direction. For example, ...
Since the yield stress in tension and compression is σy=2τa in terms of the Tresca criterion, [3.70]τa=σy/2. Therefore, [3.71]Fs=Arσy/2. Considering that Ar=P/σy, we have Fs=0.5P. The approximation of the friction law for asperity deformation yields a friction coefficient of...

When observing a rotating object, there is a force preventing the object leaving the axis of rotation; an example being the tension in a string you might be twirling a plumb bob around. However, when you are part of one of these rotating systems, such as on a child’s roundabout or mer...
What is the meaning of tension force? Give examples. What is an example of gravitational force? What is the difference between balanced and unbalanced forces? What predictions can you make about changes in the motion of an object if the forces acting on the objec...
Is tension a frictional force? Is there normal force if an object is moving? Is there normal force when something is suspended? Is the normal force an external force? Is the normal force the same as potential energy? Is tension force an example of a contact force? Is normal force part ...
Because the outside diameter of the collar is larger than that of the pipe body, the flexural stress of the complete thread at the end of the API round thread or buttress thread casing in a crooked hole is the maximum, and the vulnerable spot of tension resistance is at the external thre...
