Melde’s experiment is ideal to study the behavior of standing waves. Students can even visually determine wavelength, period and amplitude of waves.
A string undergoing transverse vibration illustrates many features common to all vibrating acoustic systems just like the vibrations of a violin or guitar string.
yes
time was not calculated at the right point so the poits of the graph were chaned
SO that the oil cup gets uniformly heated from all the sides
pulleys allow you to lift significantly more weight than without them
steel is one of the most important engineering materials on earth
When doing a controlled experiment, you get accurate results.
Observing resonance in Melde's experiment is necessary because it helps verify the relationship between the frequency of the driving force and the natural frequency of the system, leading to maximum amplitude of oscillation. Resonance demonstrates the transfer of energy most effectively, allowing for a better understanding and analysis of the behavior of the system under different conditions.

Gives you a more correct method of predicting which is the right one.
You need a control for any experiment. It doesn't sound like this particular experiment is of the utmost importance but it's a good habit to get into if you plan more important ones. I have no idea what the control would be.
The string in Meldes experiment can be made to vibrate in several ways. In most schoolphysics experiments the devices are: 1) loudspeakertype vibrator, where a rod is connected to a loudspeakermembrane and transmits the oscillations to a wire mounted on the end of the rod. 2) small DC-motor with an arm attached to the rotor. The string is attached to the arm, which moves up and down 3) electrical vibrator with coils and vibrating metalblade. The string is attached to the metalblade. In each case the device is driven by a signal-generator that outputs a harmonic electric signal.

There is no real lesson
we need to identify the precautions method in performing an experiment inside the laboratory to determine do's and don'ts and to make our experiment satisfied. Knowing the laboratory set-up is important so that we can perform our experiments easy and enjoyable.
