Required information For a bolted assembly with eight bolts, the stiffness of each bolt is kb = 1 MN/mm and the stiffness of the members is km = 2.8 MN/mm per bolt. The joint is subject to occasional disassembly for maintenance and should be preloaded accordingly. Assume the external load is equally distributed to all the bolts. It has been determined to use M6...

I keep getting the wrong answer for this problem... can anyone help? On a spacecraft two engines fire for a time of 894 s. One gives the craft an acceleration in the x direction of ax = 5.67 m/s2, while the other produces an acceleration in the y direction of ay = 9.96 m/s2. At the end of the firing period, the craft has velocity components of vx = 5920 m/s and vy = 9410 m/s. Find (a) the magnitude...

Hi. Please help with these 4 problems. I keep getting the incorrect answer and i dont know what I am doing wrong :( Thank you in advance. 1) You want to obtain a sample to estimate a population proportion. Based on previous evidence you believe the population proportion is approximately p= 0.31. You would like to be 90% confident that your estimate is within 2.5% of the true population proportion. How large of a sample size required. I got 932...
