Question 1
(a) A circular shaft used for transmission is 510mm in length and 50mm in external diameter. It
is bored to a diameter of 25mm over part of its length and for the remaining length bored to
38mm diameter. Determine the maximum power that can be transmitted if the shaft is rotating
at a speed of 210 rev/min and the shear stress is not to exceed 70MN/m?.
(b) If the angle of twist for the section with a 25mm bore is equal to that for the section with a
38mm bore determine the lengths of each section.
(c) Answer True or False to the following questions - no explanation required.
i. A stepper motor uses an outer and inner electromagnet to control the motion.
ii. Ferrous materials do not show a fatigue limit.
iii. Failure due to fatigue is not a common occurance and is limited to specific stress
conditions.
iv. For stress concentration a crack that is parallel to the load is more serious than one
that is parallel to the applied load.
