An assembly process includes a torque wrench that automatically tightens engine bolts. The wrench has a known process standard deviation of 4 foot pounds of torque. A sample of 25 bolts is selected and the average torque to which they have been tightened is 120 foot pounds. What is the 95% confidence interval for the average torque being applied by this wrench?

A wrench is used to apply a torque to a bolt. Forces F, through Fall have the same magnitude.

A wrench is used to apply a torque to a bolt. Forces F, through Fall have the same magnitude. The point of application of force F, and F) is a distance d from the center of rotation of the bolt. The application points of F). F, and F3 are all distance d apart, as shown. Use the convention that counter-clockwise torques are positive; clockwise torques are negative. Part (a) Which of the labeled forces will apply the largest magnitude torque on...

An oil company has 10 offshore rigs scattered throughout a wide area in the Gulf of Mexico. Officials feel that under normal operating conditions, each rig has only a 1% chance of having an oil spill during the year. 1. Define the random variable X. Explain carefully the distribution. 2. Find the expression of the probability mass function. 3. Compute the expected value E(X), the variance V ar(X) and standard deviation _. 4. If the rigs were located close together...

A country experiences severe storms which destroys its main resource, oil rigs. Assume that the countries economy was in long-run equilibrium before this shock happens. Use the aggregate demand–aggregate supply model to illustrate graphically the short-run and long-run impact of this supply shock on output and prices. In other word how does the economy get back to long run? Be sure to label: i. the axes; ii. the curves; iii. the initial equilibrium values; iv. the direction the curves shift;...

A) During a lab, a meter stick was used at static equilibrium (the net torque was stationary and non-rotating objects are zero) to determine the masses or unknown distances for objects suspended from the meter stick. The total forces exerted at each location along the meter stick were factored in to find the total mass of the slotted masses, the mass hanger, and the clip that was attached to the meter stick. The one mass that did not have to...
