Question 1 (2/10):
The following figure shows a rotating shaft carrying a steady downward load F at C, which is supported by
two bearings at A and B. The detailed graph near the location B shows the sizes of the shaft at its different
portions AB and BC as well as the radius of the fillet in the shoulder.
For this direct design problem, you are only required to specify a suitable material with considering the
value of F = 1000 + Q (N), in which Q is the last two digits of your student identification number
Question 2 (3/10):
The shaft in the above figure is part of a drive for an automated transfer system in a metal stamping plant.
The shaft rotating at 550 rpm carries a spur gear B having 96 teeth with a diametral pitch of 6. The teeth are
of the 20°, full-depth, involute form. Gear Q delivers 20 + 0.q (kW) to gear B, in which q are the last two
digits of your student identification number. Sheave D delivers the power to its mating sheave as shown..
You are required to:
a) Determine the magnitude of the torque in the shaft at all points
b) Compute the forces acting on the shaft at all power transmitting elements
c) Compute the reactions at the bearings
d) Draw the complete load, shear, and bending moment diagrams
e) Select an appropriate steel material for this shaft
f) Give a suggested geometry at point C of the shaft and specify the minimum acceptable diameter for the
shaft at this point.
Neglect the weight of the elements on the shafts, unless otherwise noted.
Question 3 (5/10):
A drive is shown in the above figure which is designed for a system to crush coal and deliver it by conveyor
to a railroad car. Gear A delivers 15 + 0.q (kW) to the crusher, and gear E delivers 7.5 + 0.q (kW) to the
conveyor, in which q are the last two digits of your student identification number. All power enters the shaft
through gear C. The shaft carrying gears A. C, and E rotates at 480 rpm. The distance from the middle of
each bearing to the middle of the face of the nearest gear is 100 mm.
As a design engineer, you are required to design that shaft with neglecting the weight of the elements on the
shafts
