Suppose a pulley is lifting a mass through rope so the rope is applying force to mass in form of Tension. Is the rope also applying that force to pulley i.e Is pulley being acted upon by Tension??
Tension is internal to the rope. The rope exerts contact forces on the pulley.shayan haider said:Is pulley being acted upon by Tension?
Hm but why we express Tension by Two arrows?A.T. said:Tension is internal to the rope. The rope exerts contact forces on the pulley.
Because the magnitudes of the forces exerted tangentially by the string ends are equal to the tension in the string, which by itself is a scalar.shayan haider said:Hm but why we express Tension by Two arrows?
Tension in a rope with a pulley is the force exerted by the rope on the pulley. It is the force that keeps the pulley in place and allows it to rotate.
The more pulleys you have, the more the tension in the rope is distributed. This means that the tension in the rope decreases as the number of pulleys increases.
The tension in a rope with a pulley is influenced by the weight of the load, the angle of the rope, and the number of pulleys. The greater the weight of the load, the higher the tension. The smaller the angle of the rope, the higher the tension. And as mentioned before, the more pulleys, the lower the tension.
To calculate tension in a rope with a pulley, you can use the formula T = W/n, where T is the tension, W is the weight of the load, and n is the number of pulleys. If you know the angle of the rope, you can also use the formula T = W/sinθ, where θ is the angle of the rope.
If the angle of the rope decreases, the tension in the rope increases. This is because the weight of the load is now distributed over a smaller area, making the tension more concentrated. On the other hand, if the angle of the rope increases, the tension decreases as the weight of the load is distributed over a larger area.
