A rope of length L is pulled by a constant force F. What is the tension in the rope at a distance x from the end where the force is applied

\(\frac{FL}{x}\)

\(\frac{F(L-x)}{L}\)

\overline{FL} \overline{LX}

\overline{F_x} \overline{L_x}

Text Solution

Verified by Experts

The correct answer is:

Tension at A = F .

Tension at \(\mathbf{B} = 0\) .
Assuming a linear decrease in tension.
Let tension at distance x be

\(T_x = F - kx \text{ for } x = L, 0 = F - kL \Rightarrow k = \frac{F}{L},\)

\(\therefore T_x = F - \frac{Fx}{L} = F \left(\frac{L - x}{L}\right)\)
