A 4-cy wheel loader will be used to load trucks from a quarry stockpile of uniform aggregates (1" and over in size). The haul distance will be negligible. The aggregate has a loose unite weight of 2,750 lb/cy. Estimate the loader production in tons based on a 50 min-hour efficiency factor. Use a conservative cycle time and fill factor.

A shovel with a 3.75-cy wheel loader will be used to load trucks from a quarry stockpile of processed aggregates having a maximum size of 3/8 inch. The haul distance will be negligible. The aggregate has a loose unit weight of 2950 lb/cy. Estimate the loader production in tons based on a 50-min hour efficiency factor. Use an aggressive cycle time and fill factor.

A load trucks is using a hoe equipped with a special 3½ cy light weight bucket. Working efficiency is a 45 min-hr efficiency. The material is a sandy clay, 2,600 lb./lcy. The digging face will have an average height of 60% of max. digging depth and the angle of swing will always be less than 60º. The round-trip time of either truck, exclusive of load time, is 5 minutes Consider 2 truck sizes • 18 lcy and 26 lcy. •...

The wheel of an engine starts to rotate from rest with uniform angular acceleration. It accelerates angularly for an unknown time (t1) until reaching an angular velocity of 45.13 rad / s, then maintains that angular velocity constant for 37.8 s. The total angle traveled by the wheel in total is 2398.61 rad. a) What is the angular acceleration with which the wheel began to rotate? b) What is the time (t1) that the wheel was accelerating? c) What is...

4. On a roulette wheel, the pockets are numbered from 0 to 36. The colours of the pockets are as follows: • Pocket 0 is green. • For pockets 1 through 10, the odd-numbered pockets are red and the even-numbered pockets are black. • For pockets 11 through 18, the odd-numbered pockets are black and the even-numbered pockets are red. • For pockets 19 through 28, the odd-numbered pockets are red and the even-numbered pockets are black. • For pockets...

A 3/4-6 ACME threaded screw is used to lift a 2 kN load. Note that this has a pitch of 1/6. The mean collar diameter is 4 cm. Find the torque to lift and to lower the load using a ball-bearing thrust washer. What are the efficiencies? Is it self locking? You will need to look up ACME thread size standards online for this problem

Researchers Hill and Barton used data from the 2004 Olympics to test whether one uniform color (red or blue) gave athletes a competitive advantage. In the sports of boxing tae kwon do, and wrestling, athletes are randomly assigned either a red or blue uniform. They found that out of 457 matches, the competitor in red won 248 times. Let pi be the long-term probability that an Olympic match of boxing tae kwon do, or wrestling is won by the athlete...
