A standard 25-HP electric motor operates at 1800-RPM. If the motor is connected to a pump in the configuration below. The left end of the shaft is the motor shaft and has a diameter d₂ = 1.25". The right end of the shaft is the pump shaft and has a diameter d₁ = .875" with a transitional root radius between the two diameters of r = .05". The shaft is solid, COLD WORKED, stainless steel. Determine the stress concentration factor for the shaft.

ANSWER problem 2.149& 2.150.Use x(0)=.1m and x(dot)(0)=2 as a template for answering the problem stated problem. And note theta tells you which quadrant the tan inverse value will fall in so for example theta with two positive values so the angle inputted will be in quadrant 1 (in the unit circle).Negative value from tan inverse means subtract the inverse tan value from larger value and positive value means add to the smaller value. EX: quad 2 (in the unit circle) smaller value is 90 and larger value is 180
