A bucket used in a mining operation for moving ore has frictionless rollers at points A, B, C, and D. The bucket mo...
(50) 7. Analyze the following operation. A 385C Excavator will be used to load material into a CAT 740 (no ejector) articulated truck. The excavator is equipped with a 6 cy heaped bucket and is capable of cycling every 30 seconds. The material being loaded weighs 3,300 lbs cy. The job efficiency is 90%. The trucks will be hauling the nmaterial 4000 feet over a road with a total rolling resistance of 9% to the dumpsite and 10% total rolling...
(a)A 15.0 kg block is released from rest at point A in the figure
below. The track is frictionless except for the portion between
points B and C, which has a length of 6.00 m. The block travels
down the track, hits a spring of force constant 2,300 N/m, and
compresses the spring 0.250 m from its equilibrium position before
coming to rest momentarily. Determine the coefficient of kinetic
friction between the block and the rough surface between points B...
