Fin Comparisons You are designing a part that is to have truncated triangular fins, a diagram of which is shown in Figure 1. The width of the base, t, is 6 mm, the width of the tip, t, is 2 mm. The fin length, L, is 25 mm, and the width, W, 125 mm. This fin will be used as part of a pattern with an overall thickness, trot of 12.566 mm. L W trot Figure 1: Truncated Triangular Fin There are no simple, common solutions for this geometry specifically, so you want to compare two different approximations: 1. The fin modeled as a rectangular fin using the average fin thickness 2. A triangular fin with a corrected length Le =L+tt/2 For each of these approximations, calculate a. The fin efficiency b. The fin effectiveness c. The surface effectiveness assuming the fins are made of steel with thermal conductivity, k = 60.5 W/m-°C, and are in a convective environment with a convective heat transfer coefficient h = 1000 W/m2-°C.

A 0.5-in.-diameter steel [E= 30,000 ksi] bolt (1) is placed in a copper tube (2). The copper [E= 16,000 ksi] tube has an outside diameter of 1.00 in., a wall thickness of 0.125 in., and a length of L= 8.0 in. Rigid washers, each with a thickness of t= 0.125 in., cap the ends of the copper tube. The bolt has 20 threads per inch. This means that each time the nut is turned one complete revolution, the nut advances 0.05 in. (i.e., 1/20 in.). The nut is hand-tightened on the bolt until the bolt, nut, washers, and tube are just snug, meaning that all slack has been removed from the assembly but no stress has yet been induced. What stresses are produced in the bolt and in the tube if the nut is tightened an additional quarter turn past the snug-tight condition?

Hi please help with this question thank you I just can't seem to work it out even with the given formulas. Thanks! also, I have tried these but they seem to be incorrect, or maybe parts of the calculation may be incorrect since when I submit these all together and I can't really work out where I am going wrong: sigma 1 = 73.31 MPa theta 1 = 56.87 degrees sigma 2 = 18.68 MPa theta 2 = 146.875 degrees Tmax in plane = 27.315 MPa theta s = 101.87 degrees
