A crank arm consists of a solid segment of length b x and diameter rf, a segment of length b l t and a segment of length b y as shown in the figure. Two loads P act as shown: one parallel to — vand another parallel to — y. Each load P equals 1.2 kN. The crankshaft dimensions are A] = 75 mm, fr> = 125 mm, and b 3 = 35 mm. The diameter of the upper shaft isd = 22 mm, (a) Determine the maximum tensile, compressive, and shear stresses at point A, which is located on the surface of the shaft at the z axis. (b) Determine the maximum tensile, compressive, and shear stresses at point B, which is located on the surface of the shaft at the y axis

A) Calculate the breakeven pont (in km driven) for a EV
against on HEV in Florida
of 0.1kWh/kM
Use a drive cycle conversion
5) How efficient would the powertrain of the HEV in this
example have to be to break even with an EV in Florida
after 150,000 Miles of service (240,000) km
Is it plausible to achieve the answer from pert b
