Two parts of a machine are held together by bolts that are initially tightened to provide a total imitial clamping force of 2,400 n. the stiffnesses are such that ke is five times kb (a) what external separating force would cause the clamping force to be reduced to 500 lb? (assume that the bolt remains within its elastic range.) (b) if this separating force is repeatedly applied and removed, what are the values of the mean force and the alternating force acting on the bolts?

Find the steady-state temperature at the center of the plate = /2, = /2) for sums of w from n=1 to n=19 (only odd values). find the value of n for which the change in /2, /2) is less than 1% from the value at the previous n. at this point, we consider the solution converged. does the value of the temperature at the center seem reasonable? in this part, the values of x and y are constant scalar values. you should produce a plot of the value of n on the horizontal and the estimate of the temperature at the center of the plate on the vertical. b. using the value of n (or larger) that resulted in convergence in part (a), create a contourf plot of the temperature distribution across the entire plate. use enough spatial subdivisions to create a useful plot. comment on the results. hint: you need to determine what “x” and “y” values to use to make your t matrix. i recommend using a different number of x and y values. use enough x and y values so that the plot is “smooth”.
