Figure Q1 shows a gear train consists of four spur gears A, B, C and D to be designed for a specific
mechanism. The power transmitted by gear A is 5 kW at rotational speed of 720 rpm
counterclockwise direction. Number of teeth (N) for gears A,B,C and D are respectively 20, 50,
30 and 60. The module and pressure angle of the gears are respectively 4 mm and 20o

Two 20° involute full depth spur gears are used to transmit the power and speeds shown. The material for both pinion and gear is specified as through- hardened steel tempered to 300 BHN surface hardness. Both pinion and gear are precision cut for "very accurate” gearing. For a factor of safety of 2 and assuming a diametral pitch, Pof 9. specify face widths of the pinion and gear using only the AGMA bending fatigue analysis. State all assumptions used to...

Background INFO
There are four types of blood: A, B, AB, and O (Figure 4). Each
is characterized by the glycoproteins (proteins with a sugar
attached) and lipoproteins (proteins with a lipid attached)
embedded in the surface of red blood cells (RBCs). In addition to
type, blood can be rhesus (Rh) factor positive or negative.
These proteins are inherited and may differ from individual to
individual. If, during a transfusion, an individual receives
blood with the incorrect RBC proteins (for...
