given f(x) = -2x^6 - 1.5x^4 + 10x +2. use a root location technique to determine the maximum of this function. perform iterations until the approximate relative error falls below 5%. if you use a braketing method use initial guesses of xl= 0 and xu= 1. if you use the newton raphson or the modified secant method, use an initial guess of xi= 1.if you use the secant method, use initial guesses of xi-1=0 and xi=1.assuming that the convergence is not an issue, choose the technique that is best suited for this problem. justify your choice.
If the allowable shear stress is 15ksi, determine the diameter of a solid shaft if it is to transmit 50hp at a frequency of (a) 900rpm, (b) 1800rpm
A 1.50 L buffer solution is 0.250 M in HF and 0.250 M in NaF. Calculate the pH of the solution after the addition of 0.0500 moles of solid NaOH. Assume no volume change upon the addition of base. The Ka for HF is 3.5 x 10-4.
A steel bar is attached to a wood support beam with four 20 mm diameter lag screws. The steel bar is 75-mm-wide by 6-mm-thick. For the steel bar, the yield strength is 260 MPa and the ultimate bearing strength is 350 MPa.
Write the equations required to express the shear and moment along the entire length of beam. Use an origin at point A, and then repeat computations using an origin at point D. Plot the shear and moment across the beam.
The force is applied at the two pins. The pins allow rotation around the z-axis and do not allow rotation around the y-axis. The length of the beam between the pins is 8m. Determine the maximum allowable compressive force that can be applied.
determine the velocity and acceleration of point C of the belt, (a) immediately before the power is turned off. (b) 9 s later.
Consider a diver weighing 200 lb at the end of a diving board that cantilevers out over 3 ft. The diver oscillates at a frequency of 2 Hz. What is the flexural rigidity EI of the diving board
The ¼" thick 6061?T6 aluminum bar is subjected to a tensile force of P = 5 kips. b = 4"; c = 1.5"; d = 2.5"; and the fillet radii are 1". a) Determine the maximum stress in the bar. b) What is the lateral strain in the 1.5" wide section
A powered model rocket is launched in the vertical direction. The altitude of the rocket is 100FT (above ground level) at the end of the powered portion of the flight. The rocket lands 19.676 seconds from the powered portion of the flight.
Physics two skaters with masses of 65 kg and 45 kg, respectively stand 8.0 m apart each holding one end of a rope.
