For example, if one end of a rope is attached to a wall, and the other end is attached to the floor (at an angle), if I pull straight up on the rope, would that exert a force on the wall?
You'll greatly increase the force on the wall. The (vertical) normal force you apply to a short segment of the rope must (since it isn't accelerating) be balanced by (the vertical component of) the tension forces attached to the sides of that same short rope segment (and directed parallel with the rope's extension). This is the same tension that will be connected to the wall. But since those tensions are almost perpendicular to the normal force, the magnitude of the tensions must be very large (compared to the applied normal force) in order for their (relatively small) non-perpendicular components to cancel it.vaizard said:if I pull straight up on the rope, would that exert a force on the wall?
Yes, tension can be generated perpendicular to a rope. This is known as "shear tension" and it occurs when a force is applied in a direction perpendicular to the length of the rope.
Tension perpendicular to a rope can decrease its strength. This is because the rope is not designed to handle forces in this direction and may become stretched or damaged.
It depends on the weight and the strength of the rope. If the weight is too heavy or the tension is too great, the rope may break or stretch, causing the weight to fall.
Tension perpendicular to a rope is measured using a device called a dynamometer. This device can measure the force applied to the rope in a specific direction.
Yes, shear tension can be useful in certain applications, such as in rock climbing when using a technique called "friction climbing". However, it is important to always consider the strength and limitations of the rope before applying tension in this direction.
