For purposes of analysis, a segment of the crankshaft in a vehicle is represented as shown in the figure. Two loads P act as shown, one parallel to (-x0) and another parallel to z0; each load P equals 1.0 kN. The crankshaft dimensions are b1= 80 mm, b2= 120 mm, and b3= 40 mm. The diameter of the upper shaft is d = 20 mm.
(a) Determine the maximum tensile: compressive, and shear stresses at point A, which is located on the surface of the upper shaft at the z0 axis.
(b) Determine the maximum tensile, compressive, and shear stresses at point B, which is located on the surface of the shaft at the y0 axis.
If the maximum flow rate required is 20,000 kg/h, calculate the safe working pressure of the pipe. Take the pump efficiency as 70% and allow for a pressure drop of 0.5 bar across the control valve and a loss of 10 velocity heads across the orifice..
Two ships A and B are moving with constant speeds Va and Vb along straight intersecting courses. The navigator of ship B notes the time rates fo change of the separation distance r between the ships and the bearing angle theta.
