Hello, I need the solution of this questions: The questions are in attached files.. its a "dammade with creep and fatigue" subject

Determine the lowest positive root of f(x) =[7sin(x)e^(-x)]-1 a) newton-raphson method (xi=0.3) b) secant method (xi-1=0.5 and xi=0.4) for both methods, plot a true error, et and an approximated error, ea (log scale) versus iteration numbers and discuss the rate of convergence.

this is question #6 in the attach Assignment with some corrections: 6) Consider the Warren truss shown. The uniformly distributed load w = 6.25 kN/m is suspended from joints E and G using links or cables. Use the method of sections to determine the load in member BC. NHI: Is force...

A collar B of weght W can move freely along thevertical rod. The constant of the spring is k and the spring is unstretched when theta=0. Derive an equation in W thrta k and l that must be satisfied when h collar is in equilibrium

Hello, Can you please give me the detail solution of problem 4.30 that is shown on attach file

fine, find Rt when R1 is in series with R2 and they are parallel to R3 and R4 which are in series with each other. and R1=28 ohms, R2=35 ohms R3=60 ohms, and R4= 200 ohms

Hi. I need some properties data. I'm look for some aluminum or steel alloys that can withstand high pressure and high temp. I'd really like to find a threshold table that shows this. Can you help?
