Qu. 08-18 Design a double-dwell cam to move a... Design a double-dwell cam to move a follower from 0 to 2.5 in. in 60°, dwell for 120°, fall 2.5 in. in 30°, and dwell for the remainder. The total cycle must take 4 sec. Size the cam for a 1-in. radius roller follower considering pressure angle and radius of curvature. Use eccentricity only if necessary to balance these functions. Plot both these functions. Draw the cam profile. Repeat this for a flat-faced follower. Which one would you use?

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

For the closed feedwater heater below, feedwater enters state 3 at a pressure of 2000 psia and temperature of 420 °f at a rate of ix10 ibhr. the feedwat extracted steam enters state 1 at a pressure of 1000 psia and enthalpy of 1500 btu/lbm. the extracted er leaves at an enthalpy of 528.7 btu/lbm steam leaves as a saturated liquid. (16) a) determine the mass flow rate of the extraction steam used to heat the feedwater (10) b) determine the terminal temperature difference of the closed feedwater heater
