A ½” diameter UNC, SAE Grade 8, bolt with rolled threads is preloaded to 70% of its proof strength when clamping a 2.75” thick sandwich of solid steel. Find the safety factors against static yielding, fatigue failure and joint separation when am external fatigue load having Fmax=1000 lbf and R=0 load is applied.

In a connection using 5/8-inch Φ (UNF-18, SAE Grade 8) bolts, each bolt is subjected to a varying axial load between 10 Kips to 20 Kips. Bolts can be preloaded between 0% (none) and 100%, at 10% intervals, of their proof strength. What range of preload is ideal so that the fatigue life of this joint is infinite without join separation? Use Modified Goodman Criteria for fatigue and show calculations for the preload levels between 0% and 100% (or at...

Two sections of a pressure vessel are to be held together by 5/8 in-11 UNC grade 5 bolts. You are told that the length of the bolts is 1.5 in, the length of the threaded portion of the bolts is 0.75 in, and that their elastic modulus is E=30 Mpsi. The total load on the joint is 36 kip and the stiffness of the members is given as km=8.95 Mlbf/in. What is the minimum number of bolts that should be...

The average grade in a statistics course has been 70 with a standard deviation of 8. If a random sample of 51 is selected from this population, what is the probability that the average grade is more than 72? Use Appendix B.1 for the z-values. (Round your z-value to 2 decimal places and the final answer to 4 decimal places.) Probability

A bolt manufacturer wants to investigate the machine that produces bolts with a diameter of 0.2 centimeters. If the variance of the diameters is equal to 0.025, then the machine is working as expected. A random sample of 11 bolts has a standard deviation of 0.18. Does the manufacturer have evidence at the α=0.05 level that the variance of the bolt diameters is more than required? Assume the population is normally distributed. Step 2 of 5 : Determine the critical...

We're studying the diameter of a certain type of bolt. The mean calculated from a sample of 42 bolts is 2.48 cm and the standard deviation is 0.10 cm. We're testing the hypothesis H0 : mu=2.50cm H1 : mu doesn’t equal 2.50cm a) Calculate the second species error with a significance level of 5% when the mean is 2.45 cm. b) Determine the sample size to be taken to reject a batch of bolts with a diameter of 2.52 with...

The heights of UNC sophomores are approximately normally distributed. The heights in inches of 8 randomly selected sophomores are shown below. Use these heights to find a 95% confidence interval for the average height μ of UNC sophomores. Give the endpoints of your interval to one decimal place. 72, 69, 70, 68, 70, 66, 75, 64 a) Use these heights to find a 95% confidence interval for the average height μ of UNC sophomores. Give the endpoints of your interval...

A soccer ball (mass = 0.450 kg, diameter = 0.70 m) is rolled down a 3.0 m high ramp that makes an angle of 30 degrees with the horizontal and is 6.0 m long. Assume the ball is a hollow sphere (I = 2/3MR^2) and begins at rest. How long (in seconds) would it take the ball to reach the bottom of the ramp?
