Convert the bearings in problems 7.8 through 7.9 to azimuths from north and compute the angle, smaller than 180 degree, between successive bearings. n44 degree 50'38"e, s38 degree 42'54"e, s45 degree 06'02"w, and n13 degree 24"30"w n32 degree 42'38"e, s54 degree 02'02"e, s22 degree 42'56"w, and n44 degree 35'26"w

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

Select any two (2) areas of applications of chain-drive. (clo4) a)-permanent lubrication necessary b)-hydraulic forklift truck operation c)-rigging and heavy moving materials d)-relatively high maintenance costs e)-costlier than belt drives
