Afour-cylinder, two-stroke 2.4-l diesel engine that operates on an ideal diesel cycle has a compression ratio of 22 and a cutoff ratio of 1.8. air is at 70°c and 97 kpa at the beginning of the compression process. using the cold-air-standard assumptions, determine how much power the engine will deliver at 3500 rpm. the properties of air at room temperature are cp=1.005 kj/kg-k, cv=0.718 kj/kg-k, r = 0.287 kj/kg-k, and k = 1.4. the power the engine will deliver is kw? ?

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
