Tension, spring force and weight , Physics
The pulling force that acts along a stretched flexible connector, such as a rope or cable, is called tension, T. When a rope supports the weight of an object that is at rest, the tension in the rope is equal to the weight of the object: T = mg.
Is spring force equal to weight?
Since the force the spring exerts on you is equal in magnitude to your weight, you exert a force equal to your weight on the spring, compressing it. The change in length of the spring is proportional to your weight. ... Spring scales obey Hooke's law, F = -kx.
How do you find the tension force of a spring?
For example, where R=10 pounds per inch, P=20 pounds and T=1.5 inches, you can find the pounds of force for your spring's initial tension. Simply multiply 10 by 1.5 and subtract from 20 to get 5 pounds of force (5lbf).
Does Weight Affect tension?
For a mass m= kg, the rope must support its weight = mg = Newtons to hold it up at rest. ... Note that the tension is equal to the weight only if the acceleration is zero, and that if the acceleration is negative (downward), the tension is less than the weight.
