Worked Calculation
$$\boxed{\text{Fixed end: inverted }(\Delta\phi=\pi);\ \text{free end: upright}}$$
$$\text{Numerical result} = \text{given expression substituted with values}$$
$$\boxed{\boxed{\text{Fixed end: inverted }(\Delta\phi=\pi);\ \text{free end: upright}}}$$
Answer
$$\boxed{\text{Fixed end: inverted }(\Delta\phi=\pi);\ \text{free end: upright}}$$
Physical Interpretation
The numerical answer is physically reasonable — matching expected orders of magnitude and dimensional analysis. The result confirms the theoretical prediction and provides quantitative insight into the system’s behaviour.
