What is the speed of 75 mm shaft transmitted 69.5 kW if stress is not to exceed 23.2 Mpa
You are investigating the yield stress of a specific alloy to be used in a gear. The yield stress of the alloy is known to be approximately normally distributed with o = 60 psi. A random sample of 12 specimens has a mean yield stress of 3450 psi. (a) If the mean yield stress is 3500 psi, what is the smallest level of significance at which you would be willing to reject the null hypothesis? (b) Calculate Type II error...
