Two nails are hammered into the wall at the same height off the ground and with a horizontal separation of d = 13 cm. A loop of string (mass density 4.0 g/m) is hung around the nails so that the nails are inside the loop. Then a mass m = 1.9 kg is hung from the bottom segment of string, and as a result the string forms a taut equilateral triangle. (As- sume that the nails behave like frictionless pulleys, and we may model the tension as being the same everywhere in the loop of string.) If the top segment of string were lightly plucked, what fundamental frequency f would be heard? For the limit check, investigate what happens to f if the hanging mass grows large (m → ∞). -

Q1 The moment equation for a triangular distributed load, wo 30 N/m acted on a beam (Figur Q1) with a length, L- 5 m is given as: M₂-5x³-112.5x + 125 By performing your calculation in 3 decimal points: Determine the most positive roots of the system, x by using Newton Rhapson Method. Use initial value of x = 3. Iterate until |E <0.25). (b) Determine the most positive roots of the system, x by using Secant Method. Use initial value of x= [3,5]. Iterate until E<0.25).

Hi, I need to some help for question 3. I did the first and second question. But I have some problems with the question 3. Is third question related to one and second? So please can you explain it like I am five. If it requires for number 1 I found v = 0, 48 x 106 m/s B as 0.5 T r = 2.04 m for question 2 I as 500 A n = 796 turn/m Thank you so much.
