(q4) What is the frequency of the first harmonic? Let's say you now measure the length of the string and find that it is 2 meters. You then measure the mass of the string and find that it is .0094 kg. 0.0094kg / 2 = 0.0047 (95) Using the frequency and wavelength of the first harmonic what is the Tension in the string? (1) v = λƒ (2) v = √√ (3)µ = m/l

Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing.
