I am not reallyunderstanding what this problem wants with the wording, coud you help me clarify that please? Thank you so much!! Problem 18.2An engineer wants to measure strain at a key point on a prototype part in order to estimate the stress that ispresent. Suppose that a point on the surface of a part is noted to be in biaxial stress (no stress normal to thepart surface) and strains are measured to be.x = -500µ, &y = -450µ, and Yxy = -250µ. (note that u is theprefix for "micro")Determine the state of stress in the x-y orientation. Furthermore, determine the principal stresses andabsolute maximum shear stress present in the material. Determine the planes on which these stresses actand show them (along with other relevant stresses at that orientation) on a sketch.The material has properties, E = 15000 ksi and v= 0.34

Here we have, εx = -500×10-6εy = -450×10-6γxy= -250×10-6E =15000 Ksiν =0.34

basically we’re designing a machine that has rollers to flattened and rotating shaft to roll a strip of dried leaves into a bundle. Now we were advised to provide calculations with the relevant engineering parameters including the sizing of gears, belt and pulley, the torque requirement of each machine element and the power rating of the motor. The entire machine is powered by a stepper motor connected with a timing belt and pulley for power transmission. and gears that will rotate the shaft. Can you give us the flow of calculations from the rollers, the rotating shaft, up to sizing pf belt and pulley and gear ratios, with the last step as finding the power requirement (in hp) of the entire machine?

The length of each arm is 150 mm. The stress on the arms and the spindle must not exceed the yield strength of the material selected for neither of the two analysis positions. b) Using the mechanical properties of the material you selected, calculate the change in dimension that the arms and the spindle of the jack were tested for the two analysis positions. The length of the spindle is 280 mm.
"Your boss requests a recommendation on which process to use to make fillet welds on stainless steel rail tank cars with this material. Your heart beating fast, you respond. " A: Use HYPERFILL®. The cooling rate is acceptable for this material and productivity gains are important given the large size of the product. B: "Use HYPERFILL®, for the same reasons as (A), BUT we need to change materials to a low carbon stainless steel (e.g. 304L) or we will get corrosion failure in the HAZ." C: "Use GMAW-P. For this material, this heat input is best. " D: "Use GMAW-P, for the same reasons as (C), but we need to change materials to a low carbon stainless steel (e.g. 304L) or we will get corrosion failure in the FZ."
