A natural gas pipeline is being built for service in low temperature conditions. At the expected temperature, 8 OD inch nominal pipe of ASTM A334 Grade 8 alloy steel material is to be used. The material has Sy ~ LN [75.4, 3.0] ksi. It will be subjected to an internal pressure load of P ~ LN [2.5, 0.6] ksi. Assume you can use the thin-wall pressure vessel equation to calculate the hoop stress. a. What is the value of z that corresponds to a reliability of 0.999995 against yielding

Aflywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. determine the total number of revolutions of the flywheel during the period of its acceleration. a.5.65 b.8.43 c. 723 d.6.86

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
